I am running an Athlon 3000+ Venice and an Abit AN8 Sli. I have pushed my Hypertransport as high as 300mhz (300 x 3) without any issues. I didn't go higher because I figured that would be high enough. I found that my CPU would run at 2.7 ghz (300 x 9 1.5v) but would fail Prime95. 2.7 I backed it down to 2.61 and it seems to be running stable at that speed. I have only run Prime95 for about 15 minutes, and gone through 3D Mark05, I'll test it more at 2.61 later, but for now it seems stable.
The problem I'm having is to achieve the above speeds I have to have my memory set to 200mhz. When I was in Windows at 2.7 and ran CPUz it said my memory was running at 150mhz. My understanding of this (and could be wrong) is that it's running at a ratio, because my HT was at 300mhz, a 50% overclock from stock, my memory is at this same ratio. Even though I had it set to 200mhz it is actually running at a ratio, and running at 150% of the stock 100mhz DDR speed, or 150mhz. So, in theory I should be able to run my PC stable at 290 x 9 = 2610mhz with my memory set at 266 (133 x 1.45 = 193mhz, or 386mhz effective DDR speed) but when I set it to this speed the system beeps at me for a while then all the bios settings default back to the stock speeds. I have pushed my memory all the way up to 2.9 volts (2.6 stock) to see if this would remedy the situation. My memory is Corsair Value Select CAS 2.5. I know it's not fast stuff, but I don't understand why it will not run at 386mhz, that is slower then it's rated speed. When I leave the CPU at 1800mhz 200mhz HT then the memory has no trouble running at 200mzh (400mhz effective DDR), so I don't know what is wrong. Does anyone have any ideas?
Here's the specs of the system.
Abit A8N Sli
Athlon 64 3000+ Venice E6 (stock retail cooler)
1 gig (2 x 512) Corsair Value Select
Antec Neo HE 500watt
eVGA GeForce 6800GS 490/1.1 (Factory oc)
My temps at load fluctuate between 49 and 52.
Thanks in advance!
