Well I decided to build another computer. I got a A8n-e with bios updated to 1011 and a venice 3000+ E3 lbble 0517 apaw.

I looked at NCSA's link for the sli version, and started the fun. I wasn't sure about the divider so I left it at 400Mhz. I changed my bios configurations to what the screenies he had on.

At this moment the HTT is 227, Multi is 9, Voltage is 1.450. I don't expect too much from using Corsair 2x512mb Valueselect Ram, but shouldn't it go further? When I drop the Ram to 333Mhz, I got up to around 265 HTT. I was told by a chum that by dropping the ram speed it lowers some other part of my speed jsut to boost cpu speed, which isn't always quality. The temperature for the 227 HTT X 9Multi at 400Mhz ram index is around 42C.

Also I am using a temporary HDD to boot into windows so I can do Prime95, would putting my Raptor 74gb make a difference?

Any helpful advice is appreciated. Thanks.

No the Raptor will not affect overclocking, but also if you want your RAM to go higher try boosting the vDimm voltage some, also what timings is it at? Corsair valueselect is very good RAM (for value ram) my DDR2 533 runs up to DDR2 700!

Not much difference when your htt is that high..Have you dropped your HTT multi to 3 because 265 would take you over the 1000mhz range and o/c will become unstable and may corrupt windows.....i runn a 333 divider @270mhz with ram @225mhz and tight timmings

 

[AznKwaiJai]

Well it is a ddr1 so it is a DRR 400 / PC3200 with 2.5-3-3-8. What's this about me wanting my ram to go higher? Do I? I'm actually a newbie at this.

I did drop the HTT multi to 3 when I was using 333Mhz ram with 265HTT.
But at this moment, the ram is at 400Mhz. The ram seems to be running at Frequency 227 Mhz. What does tight timing actually mean?

The HTT and the basic math.
It defaults @ 5x200=1000 You want to keep that between 800-1000. Slightly over 1000 and you will experance instability.
So if default is...
5x200=1000
4x for 201-250
3x for 251-333
Don't confuse the RAM's basic setting with the above.
Changing the RAM's basic setting will involk a divider for the CPU to RAM ratio... if you get crashes as the HTT increases follow the 5x, 4x, 3x, math and set the RAM to 333 or even 266 if necessary.

NOTE... @ 265 x 4 your at 1060 and pushing for instability so the 3x is correct for a 795 which allows for more HTT increase

So if I drop the RAM to 333 then maybe 266, when do I know when to stop? Isn't the lower my RAM goes, the lower the speed quality of the CPU? Or RAM 400 to 333 to 266 isn't that big a difference and I should just drop til I can drop no more just to see the limit of the HTT?

 

[The Duke]

Drop the RAM to 266 to find the CPU's max stable speed.
Once you found that try upping to 333 and test the RAM with Memtest86
Check out the Memtest in the link... there is a handy how to Quick Test... if all is well then do the very long full test

LOTS of great info there for you

I'm testing RAM 333 at this moment and reached 275 HTT rite now and still climbing. After I find the max of 333, then I'll try 266. Or should I just stop 333 and jump to 266?

I looked at NCSA's faq on that board many hrs. That's how I got this far. But my ignorance limits me.

Okay, I just found it stable at 298HTT at RAM 266. What do you mean "try upping to 333"? If I change the divider from 266 to 333, wouldn't it cause my computer to fail its Prime95? Or do you mean, just leave the HTT at 298 and change the RAM to 333 and do the Memtest86 test at bootup?

Maybe this would help.

Any help?
