hi

i got new cooler and pushed my system a bit higher but got into few problems
1)when ever i go over 300MHZ FSB it start showing small black blocks in windows
2)My ram cant cross the 900MHZ whis out going unstable

im now at 267FSB on 3.47GHZ @ VRAM:+0.2V VFSB:+0.1V VCORE:1.331V ,when ever i go higher to 270FSB @ 3.51GHZ i cant find the solotion to stablise it ,i raised| |VCORE to 1.35V| |VFSB to +0.2V| |VRAM +0.2V and still PRIME95 sais error on the 7 test in first round of 1024K ,did i richd my chip end wall ?
what should i try next ?

and i cant get my RAM:FSB 1:1 any help will be apreshated

my laitest sys info in my sig


thank you ,

You're probably better off locking your ram at its stock speed until you stabilize your CPU. It's much easier to OC when you are only dealing with one variable at a time. You can raise your vcore and motherboard voltages all you want, but if its your ram that's giving you errors, none of it will help. Most of the time adding voltage to ram is a bad idea and doesn't help very much anyway, especially with generic ram.

I don't know if you have to overvolt your RAM that much - try backing it off a bit. Have you upped the voltage on your Northbridge (not the FSB)?

If that's integrated graphics you need to go into the Bios and lock the PCI and PCI-E Frequency, otherwise when you raise the FSB they raise also. Which can damage you GPU.

Set PCI to 33Mhz
Set PCI-E to 100Mhz

those are some really loose timings and the performace increase you are going to see is not worth the timing change. It seems like you might have hit a wall or you need to upgrade your ram.

You should try locking your ram at its stock mhz and timings(un-link the FSB and ram if you can). Your ram is not designed to be overclocked, so you should leave the work up to your CPU only.

that the problem i cant lock it
i set it to its original 800MHZ
but the timing i run at 6-4-4-17
post #10 of 12
Can't you set the timings to what they should be manually?
