Problems with new RAM

post #1 of 3
Thread Starter 
I have recently gotten some new PC2-6400 (400Mhz) ram, two sticks at one GB each. At first i put them in with my old two lots of 512, so all four slots were full. That seemed to work with no problems, but their frequencies were limited to about 260 or something, brought down by the old ram.

I had raised my FSB to about 235 so that my CPU speed was about 2350 and my RAM was at 294 Mhz. I decided to take the old ones out and just have my new ones. AT first it never even made past the loading screen, as the OS booted it went to blue screen for half a second then restarted. I lowered the FSB to stock 200 and increased the HT link back to 5 so everything was normal.

However, even though most times after that It booted ok and I managed to log on, once when I opened a program the screen went black for a second, and then once when I alt tabbed from a fullscreen program it just resarted.

I increased the RAM voltage by 0.05, I think it was, and after logging on the text underneath the icons was black and blurry, and all the buttons on taskmanager were blank... So i changed that back..

I am currently running an Orthos test, the first time after only a few seconds it came with an error, saying

"2:Test 1, 4000 Lucas-Lehmer iterations of M19922945 using 1024K FFT length.
1:Test 1, 4000 Lucas-Lehmer iterations of M19922945 using 1024K FFT length.
2:FATAL ERROR: Rounding was 0.46875, expected less than 0.4
2:Hardware failure detected, consult stress.txt file.
2:Torture Test ran 0 minutes 16 seconds - 1 errors, 0 warnings.
2:Execution halted.

but then I ran again and it's still going Ok now.

I would like to be able to increase my FSB back to 235 or so, to increase my cpu clock speed. What will I need to do to make my RAM work properly with it? I can manually set the frequency number thing from 800 to 666 i think it is, the one inbetween 533 and 800, what would that do?

Anything I should change to make the RAM more stable?

Also, I have decreased the FSB back to the standard 200 and the multilyer is the standard 10, but it shows my clock speed as 2009.4 MHz and the memory frequency as 402 instead of just 400. What are these small errors due to?

If you could tell us the brand and model of the RAM, it would be helpful. I reckon you could go ahead and set the RAM voltage at 2.1v which is about what most PC6400 RAM is spec'd for (give or take 0.1v maybe). Make sure your RAM divider is 1:1 (or 2.0 it will say possibly - means the same thing). This will simply double your FSB for your RAM speed. This will let you run up to a 400 FSB without your RAM being overclocked. Your running of a 235FSB is very low, but I don't know much about AMD CPU's so maybe that's normal.

the ram is OCZ Gold Edition. How Do i find that ratio in my BIOS? and why wouldnt my ram work normally when i have the normal settings on? Weird things happen like Zone Alarm saying anti-virus scanning is disables, and this can be due to "bus speed clocking or antivrus updates disabled", and random application errors... At the moment i manually set it from the the auto of '800' to 667, and it seems to be working fine.

But i dont want to keep it at that since its not the potential speed. What will I need to do to make the ram operate with stablility?
