Look at your signature and I think you'll find the answer.

You don't have an NForce4 SLI chipset, your's is different.

You might get a reply from them saying they are working on a new version of clockgen hopefully.

Edit: Ah, I saw your other thread. Fixed huh?

Q. What is GPU? 

A. Graphics processing unit. Your video cards processor.


Q. Last night I rechecked Bios and nearest to HTT is :
"Over Voltage Hypertransport" [Disabled]  or Enabled, with no figures to set.

A. This is a setting that is missing on my board, it enables volt increases for the hypertransport link allowing massive overclocks. Leave it disabled until you have expert knowledge of overclocking.


Q. DDR Vcore [Auto] ....2.6V, 2.65.........to 3.2

A. Normally called Vram. Set this field to manual if your ram is unstable at high overclocks, increasing ram voltage will yield stabilty at higher speeds. There is a danger of burning out your RAM if you use this. There are special RAM testing and burn in programs for getting the most out of your RAM.

Most RAM for these rigs is 2.6V, but you can probably go to 2.75V without harming anything. Ground yourself to the case and feel the ram chips with the back of your fingers to see if they are hot while flying in FS9 or using some intense benchmarking utility. If they are hot, do not increase Vram.


Q. DDR Clock Skew  [Auto] ....Normal, Advanced, 150 - 900pc

A. I wouldn't have a clue except that it's an advanced overclocking option, leave it at default until you know for sure what it does.


Q. 1T / 2T Memory Timing 1T / 2T

A. this is a basic RAM command rate timing. The boys at the overclocking sites will tell you that 1T is a must. Well, that's just a load of BS with these boards. I can get better performance using 2T with my RAM, and in fact, it's been documented by several people that these asus boards are unstable at 1T in many high speed configurations (ie. When memclock goes much over 240mhz).

Use 1T under 240mhz but if you tighten the other ram timings you may find 2T will need to be used. Proof of performance needs to be carefully tested with a benchmark utility to find which configuration is the best.


Q. Vcore Voltage      [1.472v] ....Ignore

A. Definitely do not ignore this setting. The Vcore you have set there is VERY high for Stock cooling. You should see sharp temperature rises while Simming or benchmarking. Be careful. Only increase Vcore from standard 1.4V if your rig is unstable at the overclock, and increase it in very small increments until stabilty is reached. I would leave it at stock speed until you have crashes or benchtest failures.


Q. I am stuck, unless any of the other variable factors in the Bios that I can see, can be used instead of the elusive HTT,  like:
1. CPU FSB [200] goes up by 1, 2, 3 ......to 500

A. CPU FSB is the same as HTT. This is what you are winding up with the slider in Clockgen.

2. Processor Voltage (for setting VCore) starts at 1.735,
is Set at [1.425] ....1.4375, 1.45, ....to 1.5625

A. This is different from the info you provided above for Vcore (you said it was 1.472v). You have to be accurate or I'm wasting my time replying ok?

3. Adjust PCIE Freq Set [100] …101, 102 103......to 200

A. Leave this at 100mhz always.


4. How about mem, came up same value as HTT

A. Yes, that's right, the Memclock is identical to the HTT or cpu/FSB speed when there is no ram divider set, in other words, the memory bus is running in sync with the FSB. This changes if you use a memoery divider ratio or a half cpu mulitplier such as 10.5x



Q. Processor Freq.Multiplier is maxed [11x]. 

Set this to 10 x or less when experimenting with other settings, this takes the CPU out of the equation when searching for stability of HTT and RAM speed. It also allows a smaller multiplier to be used to keep the CPU speed in operating range when the FSB is overclocked a lot.


Q.  BUT this in Bios is not so simple to pinpoint, seems very complecated. 

A. It's complex because it is a bios designed for advanced overclockers. I wish I had it, mine is not complex enough to tweak as effectively.


Q. From Memory Settings goes to Northbridge Chipset config which goes to Memory Config and on & on.

A. Another set of advanced features, leave the Northbridge settings alone. They are for extreme overclocking. The memory config is probably where you will find your RAM timing settings, possibly the most complex set of options you will need to deal with if you seek absolute performance. Adjusting RAM timings can easily cause a system boot failure and a need for a CMOS reset by mainboard jumper, be careful with those timings. Just because you read that someone uses a set of timings does not mean that it will work on your machine. Set defaults then do a lot of reading about it.


Q. BTW you ruined your nice pet with glasses & those teeth, looks as if he is with rabies.

A. That's my boy you're talking about!

Since previous thread, after a couple of B...up with failed bootups & restarts, I altered the Bios items   1, 2, 5 & 10 only, rest are defaults.

PS. Clockgen sliders taken to CPU 2422,
with these showing up on their own: HTT 220, Mem 110, PCIE 100, PCI 36

CPU Heat sink, Ram, Chipset & pipes were cool to the touch, 6600gt was warm.

Bios now is reset to defaults.

If the Everest report is of any use I can send it to you.

You realise ofcource that the settings I put were not from a consious efford, more rather out of a flook, to arrive at 2.4ghz.

But Everest again says O/clock 10% as with 2.2ghz.

I do'nt know about instability, but PC was normal, fs9 flew well, and did not noticed any improvements in my heavy clouds etc. Just as before I would say.

Heavy multitasking is not affected either.

Will try, but do not remember to have seen Vram.

My corrupted ClGen comes up like this below, and mine as per your last one. So different. I keep setting Clgen up just to see, even if it is unusable. Hoping these interrilations would be same if it was working & applied.
Is,nt there any other similar progr. for windows?

So you reckon it is because of the x16 of my chipset?
No word from ClGen people yet.

Also Everest Temps are of Computer > Sensor. Has nothing else. Unless the mobo corrupted this one too.

PS. would you say that "Voltage Control" in Clgen refers to CPU VCORE? I get confused as I find everything is referred too differently at different places.

Tahnx for the info.

I put in the figures you said:
Vcor 1.337, FSB 220, Cpu Multplr 11, VRam 2.7, Hypertr.Multplr. 4.
It gave Cpu Spd 2419mhz, but fs9 was rather Jerky.

Then entered:-
Vcor 1.450, FSB 240, Cpu Multplr 10.5, VRam 2.60, Hypertr.Multplr. 4,   and raised "Mem Lock" value [200]
It gave Cpu spd 2519mhz, 20% up, VERY Unstable.

Then:-
Vcor 1.450, FSB 240, Cpu Multplr 10.5, VRam 2.60, Hypertr.Multplr. 4,  and returned "Mem Lock" value [100]
Gave Cpu spd 2519mhz, 20% up, fs9 fly well, little jerky low over LHR buildings, clouds / rain very slightly down, & multitasking OK.

StressPrime gave Ts as per foto.
CPU, Sticks, Chipset lukewarm & 6600gt slight heat to the touch.

Temps, out of fs9, CPU 30c, Chipset 34c, the others 31c.

Not much idea of what I was doing mind you, but anything else to try?

But that SpeedFan "Vcore1" modulating just below 1.50v

Where is the "Memory" value of ClGen represented in Bios, confused as always.

3DMark2001 gave 7007, whatever that means. Temps OK.

How is the 6600gt limiting fs9?

By coincidence, since I started this caper 3 weeks ago, the Bootup is slow 35secs with "Welcome" showing then 45secs with empty blue screen before the desktop fills up.

PS. does this show that "Vcore is under control"?

I said to a friend on the phone that I started to learn O/clocking and he sent me this. Safe as an exersise?.

CRACKEY?! what with:

DDR VCORE  = VRAM
VCORE         =  PROCESSOR VOLTAGe VOLTAGE
 -  " -           =   Voltage Control in ClockGen

Now with  " Ram Volt", "set your Ram 266", "increase ram & timings", "set ram timings"
I wish terminology was universal.

"I would use the bios and forgo programs like clockgen and ntune. The biggest problem I find with them is that once I change settings I often have to reboot to get the system back to the bios defaults as they do not often set correctly.
Set your ram to 266 for the purpose of excluding it from the cpu testing. Once you get your maximum CPU then you can increase the ram and the timings. Set your ram timings high as well. 3-4-4-8. It is spec'd out at 2-3-3-6 so once you get your CPU at maximum you will have lots of room to play with it.
Try these settings:
10x multi @ 240 --> 250 --> 260 --> 270
pci-e 100 mhz
ram volt 2.8
cpu volt 1.4375
pci sync 33.33
Test each increase with superpi 32m. Once you reach instability you can drop by a few increments and retest. Once you are stable then you can prime95 test your system for stability. Drop incrementally again until you reach prime95 stabilty.
You can also increase the voltage to 1.55 also to find your maximum. That is a Venice CPU so you should be able to hit ~2.6 - 2.7GHz."

I was writing this when your last thread arrived.

Apreciate a lot your concern and WARNINGS.

1. As mentioned before, any settings I try only stay up to the readings after StressPrime & a quick few seconds to check temps with fs9 & multitasking then back to defaults.
The case is open in front of me continusly feeling the Cpu Heatsink, sticks, chipset & pipes, and the 6600gt. They were never hot to the touch, just worm as discribed on each O/clock try.

2. Made a mistake referring to Temps in last foto as "StressPrime gave Ts as per foto."

Those as foto shows were with fs9 running, all maxed, full cloud & moderate rain.

The AFTER StressPrime test teps are, in this foto.

That test's CPU Usage never goes past 3 - 4%, in fs9 are 100% constantly. Would'nt that be a better test? after seeing the StreePrime ones are low?; or am I confused again. Wont be the least surprised.

The VCore is 1.4125 default. To O/clock lowered it to 1.335, nearest to 1.34 as you said, giving Cpu Speed 2.1.

There are some facilities here, maybe relating to this?.
Advance > Jumper Free
Over V NB core [Disable] or Vcore to +1.3
Over V SB             -"-               - " -     +1.6
Over V Hypertransport [Disable] or from +1.2 to+1.3            

luke

Thanx again Congo,
I think I tried to explain this before, but with VCore at 1.335 during the test shows 1.50 & before/after it 1.39.

It is terrifying that I could burn my £85 6600gt & £105 mobo, when Temps are 30-40c and on the touch all are lookewarkm with the click of a key.
This is not for the low on cash & faint at heart.

I am painting the kitchen sealing right now, but after will sent the settings and the fs9 running results.

Had nTune, C&Quiet installed but not running or enabled.
Uninstalled both.
Speedfan now reads VCore1.39 during the test.
What next?

Tryed the FFTs,
1st used Vcore 1.3375 to get true 1.39 &
2nd used 1.325 for 1.47.
CPU Temp Diff was 39c & 44c

Only  PCI settings in Bios is PCI Latency Timer 32, [64] ...up to 248

Is Ram speed my Corsair's 400mhz (DDR) ?
What is MemCLOCK you mention?.
In Bios I saw Mem Clock  grayed ot at 200, then MemCLOCK MODE > Limit > MemCLock VALUE 100, 133, 166, ...to 250.
Then MCT Timing [Manual] > CAS, TRAS, TRP, TRCD etc.
Is Cpu spd  called Core spd?

Where is "Ram Timings 3-4-4-8" & " 2-3-3-6 spec'd out'' & "Ram Volt 2.8" & "PCI Sync 33.33" that chap saying to try?

what & where is "Ram Devider [166] & Ram 200mhz you suggested to try?

In "A64MemFreq11" is Ref.Clock the Cpu spd?
What is CPU Frequency?

Still have issues with differing phraseology for the same things.

My Manual does not correspond to my bios  AMI 64-1009-009999-00101111-121405-C51G, but I found the correct one here:
http://dlsvr02.asus.com/pub/ASUS/mb/socket939/A8N32-SLI%20Deluxe/E2280_A8N32-SLI...

Here are the attempts mentioned on previous threads, tabulated.
Trying to find the correct sequence to put them & help remembering terms & actions to take.

I suppose there will be more columns to be added later to cater for ram & other variables?:-

I'm sorry Luke, I wrote an answer that took 2 hours and then I clicked the box shut and lost it   

The top 4 timings in the top chart you show there are the fabulous four ram timings.....

CAS (Tcl)                              3
RAS/CAS delay (Trcd)           4
Row Precharge time (Trp)    4
Min Active RAS (Tras)           8

Those are relaxed timings, you can clock higher with them relaxed, sometimes it can be beneficial.

Those are instructions for max overclock, and they are not accurate anyway, once you find max RAM, max CPU and max HTT, that doesnt mean you can max them all out, they all have to be stable together, at least maxing out gives you some guidlines and shows any weaknesses.

When messing about with clock speeds, it's easy to forget the implications on the system as a whole because of the inter-relationships of the speeds and multpliers on different buses.

As an example, say you were testing 240mhz, 250mhz 260mhz..... as you mention above. Say if you were testing the CPU for max speed and you got a crash at 240mhz, you would think, "oh bugger, that's it then...."
But that may not be it, did you forget to change the HT multiplier to 4x to accomodate the change? Is the HT bus now running 5 x 240 = 1200mhz ! thus crashing the HT bus, nothing to do with the CPU at all!

Also, remember to adjust voltages consistent with your clockspeeds where required, not enough juice, won't work, too much juice, heat and failure issues. Monitor temps.

Disable any auto fanspeed software while trying to determine how temperature is affected by settings.

" Tryed the FFTs, 
1st used Vcore 1.3375 to get true 1.39 &
2nd used 1.325 for 1.47.
CPU Temp Diff was 39c & 44c "

Those figures don't make any sense at all, I hope this was your error and not real, if it was real, it indicates that some auto software is still dynamically controlling voltages, a definite no no, and brings me back to my previous mis-givings......

Are you absolutely sure you have voltage under correct control and is this demonstratable?

Quote:



Perfect! Ok, great. You just demonstrated it.
It's not you, it's because we started with software you couldn't run and then you got thrown in deep.

I can tell you have a pretty good grasp of the system by now. As long as you monitor temps and voltage when you make changes, you should be fine.

There are some decent overclocking guides out on the net as you probly know.

http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2548&p=4

I just did it again, I wrote 2 pages over the last two hours and then I lost it all. I actually had just cut the text when I got a popup because I had accidently held my shift key down too long. I lost the text.  

Ask fewer questions at a time, this is really pissing me off.

Your memory must be automatically setting a divider for you because it's set to auto or you have the wrong manual settings, so it sets a usable divider and timings so it boots and you don't just crash.

I did go into great detail about the chipset blah blah blah, can't do anymore on this today.

Your temps are fine, looking at trouble if the CPU gets over 60*C

The graphics card is at it's limit in FS9, so you only get the benefit of the small overclock for the processing and throughput of FS9, not the graphics rendering, so you will see minimal, if any visible difference. If you had a 7800GT installed, then you would notice the effect of the overclock a lot more, however, 8 - 10% is not a big overclock, usually a 10% overclock will smooth out a marginal game or perhaps allow a higher setting to be used. I'm overclocked 34%, and you see some real benefits at those speeds.
