1T command rate is 10% faster than 2T command rate. Some RAM can do 0T, but i don't know of any.

Command rate is the amount of clock cycles the chip select process needs before it can be executed.

My bad, I was asking if his RAM timings were at 1T or not. lol I guess I should have been more clear.

BTW, I've never heard of RAM at 0T before, let alone a motherboard that supports it.....

Oh yeah, I just eBayed a Venice 3800+, so we'll see what I can do with it when it arrives in the mail. All I want is over 3000 MHz. After that, it is just bonus. Grin

I just spent an insane amount of time testing out what my new hardware is capable of for the sake of very small performance gains over my first ten minutes of tweaking. I'm talking about a wasted week here, not just a few hours.

Was it worth it? Well, yes because I learned a bit, and no because the performance increase I made was negligle over my original overclock. Also, the extra stress/heat on the system really can't be justified at the extreme end of the overclock.

However, I made substantial performance gains over my hardware's stock speeds with a moderate overclock that is not reliant on excessive voltage/heat/stress tweaks. In that regard, this whole exercise has proved successful. I also now have enough knowledge to be confident in my settings finally.

With my setup, I could never improve on a 1:1 ratio, I ended up with the following configuration which I will probably reduce by about 5mhz.

HTT = 275mhz, HT multiplier 3x, Memory @ DDR 550 @ 3-4-4-8 2T & 2.9volts, CPU @ 2750mhz (10x 275mhz) & 1.46volts.

This gave me a system bandwidth of 8808 mb/sec and a memory throughput of just over 7000 mb/sec.

Heat Considerations:

I found my chipset fan/heatsink on the mainboard was a joke, I put my modified P3 cooler back on the NF4 Chip and it's now running very cool finally.

I also found that I can't set my RAM volts any higher than 3v on this board, and it seems to run as well at 2.9 anyway. I actually had a little instability at 3v for some reason.

My Ram came fitted with heatspreaders and was running extremely hot. There was a strip of heat transfer tape between the ram chips and the spreaders. I removed the spreaders and the temps may have decreased slightly, but they were still too hot so I removed the tape from the spreaders and put some heat transfer compound on them instead. This made all the difference and I could now feel the heat immediately transferring to the spreaders. Still quite hot, I placed a case fan beside the mainboard blowing along the RAM's heatspreaders and now the RAM is running very cool indeed.

My CPU temps got up to 58* in the heat of the day during stress testing at max CPU stress (at 2930mhz) and voltage of 1.6v. I backed off the voltage and CPU speed a bit and now the CPU rarely gets over 48*

All in all, I'm very happy with my air cooling now, and the CPU is fine with the supplied AMD HSF assembly at this large overclock!

Thanks for all the help Nick N !

Your welcome Cheesy

May I suggest this HSF:

http://www.newegg.com/product/product.asp?item=N82E16835106038

The AMD stock HSF is very good.... the one from the link above is 100% solid COPPER and will probably reduce your temps 5-10c. At 1.7vcore under full load I top out at 53c. The 3 blade, deep pitch (like a boat prop) fan is insane and overkill but it comes with an external tower/case dial to set the max RPM, which in my case I have it set to 2600RPM. I modified the power connector so I could plug it directly into the motherboard CPU fan header (it comes designed for a PSU plug) so in Windows, SPEEDFAN controls when it kicks in to 100%. It idles it at 1200RPM... virtually silent either way. The fan can run 6000 RPM and sound like a vacuum cleaner so if you would like to experiment with higher voltage on air-cooling, it will definitely handle the heat, NO PROBLEM. .. Its just insanely loud at that speed.

I'm pretty happy with the CPU setup at the moment, except it would be nice if I could run it at 2.93ghz stable, which at the moment I haven't achieved.

My goal for the RAM was to run it at 283mhz (DDR566).
Right now it's just not quite stable there, this morning I could only get it stable (with everything else pumped up) at 278mhz, it was really hot and steamy today.

I think I'm at about the limit for this rig on air cooling, the ambient temperature is just so high.

Awesome Nick!

I've got some new respect for that VIA chipset now, it's performance is right up there. If I back off my FSB to 275mhz, there is really nothing between our 2 rigs.

I was leery about the VIA chipset as well but from the forums I read prior to the purchase it was apparent the A8V Deluxe was not suffering any VIA problems as long as the VIA IDE and AGP drivers were not installed. The A8V Deluxe performs best using the default Microsoft IDE and AGP drivers built into WindowsXP SP2. I tested every BIOS from 1009 through 1016 beta and found 1014 to be the best. I had to laugh a bit about a big buzz in a few O/c forums where so called "experts" were discussing the divider being mathematically incorrect above BIOS 1009. After investigating it I found ASUS fixed the divider math to correctly reflect the A64 system in BIOS’s above 1009. Allot of people, including 'experts' do not understand how the A64 divider works so they think their systems are unstable when using any BIOS above 1009 on the A8V.

Poor buggers. I had no such pre-concieved notions and just watched perplexed as the system did all kinds of wierd settings. Hey, as long as it boots right?

Grin

I'm just gonna recommend clockgen from now on, it provides a graphic display of the relationships between the clock speeds, even though it's not clear at first how those are derived.

I do not understand "fk Thermaltake"

If it means what I think it does, all I can say is I do not trash a company name, only individual products that do not function within the specifications they advertise, or the specifications I require as an engineer for my systems.

The HSF I mentioned above well exceeds my requirements and performs well within the advertised specifications. That does not mean it will work the same for everyone in every ambient/humidity/O/c condition.

Yes it means what you think. I never had a problem with them but when I constantly see them ripping ideas/products off of other companys (Zalman is their latest victim) it bothers me. I also have had 2 cases from them. Both arrived broken. One the front door had hinges broken and shortly fell off. The other the front panel lighting scheme broke almost immediatly. They do make one good product and that is the Sonic Tower.

Anyway an XP-90 or XP-120 from Thermalright will kill anything Thermaltake has to offer. IMO Thermaltake more about looks then funtionality.
