I installed the gear into my system.

I'm running the FSB at 260 with a 10x CPU multiplier giving me 2.6ghz and 520mhz DDR for my new RAM.

No voltages increases required for stability as yet at these speeds and there is no noticeable Temp increase in the CPU either.

Chipset seems quite warm though   

This CPU costs $350 here in Australia. An AMD FX57 costs $1500 here, and they seem to be essentially the same CPU, even if a "little" effort is required to extract the best out of it.

I thought my 3500+ Venice CPU was fast, this 3700+ San Diego is noticeably faster in all aspects of my daily computing.

Anyone after a single core performance CPU need look no further than this beast.

They are expensive here and those models at OC'ers aren't available thru my contacts. I would have paid £148 for this one, but it was a gift  

I was following your posts in OC'ers as well Jimbo.

I decided quickly on this CPU from the good things I read, particularly how it stays so cool. It has SSE3 instruction sets that the Opteron lacks as well.

I started having problems with my PC4000 ram getting out of range as I approached 2.9ghz on the overclock, so I backed it off. I don't want to run a bus divider.

Looking to sell the 3500+? I run water cooling, and I run into a limitation of "FSB" on my 3000+. I think a higher multiplier would help me loads. (current CPU temp: 86 F)

Here are the benchmarks for 250FSB @ 1000-HT:

PS:

You need not worry about an A64 overheating.... at all

The A64 will automatically shut down if the temp exceeds 75-80c with absolutely no damage to the processor. AMD was very smart to include that E-shutdown system starting in their A64 line of processors. It works very well, so well in fact that when the clip broke on my CPU heatsink and the HSF fell to the bottom of the tower while I was using FS2004, the system simply haulted. I opened the tower with it still running to find the HSF had fallen off. I shut the tower down (it ran at least 2 minutes after the HSF had come off the processor) ... and replaced the clip with a spare I had.

The system booted up like nothing happened.

Temps are no longer an issue with the A64 processor.

Ah!  Good deal.

Well, enjoy your new found overclocker! 

1T?

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.

Your welcome 


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.

Here is my Everest report (condensed) at today's settings......

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.

OMG!

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?



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.

Guilty.........  I trashed Dell for years, only to find out that they made fairly competitive notebook PC's.

Never trashed Dell infact I have refered people to them that don't want a computer built or need a budget computer. Now Gateway on the other hand....
