Unexplainable problem??

post #1 of 29
Thread Starter 
Ok...I posted something like this earlier...now I have some more tinkering figured out...

I can run my processor at 2640 (240x11)...but I can't get it stable at 293x9 or even 300x8 or 300x7....it isn't prime stable with 300 until I get to x4 multi.

Now this is where it gets weird. I put my ram on a 2:3 divider...so the FSB can run up to 300 without going over stock speeds for the ram...then I can figure out from there...right? well ok.

So I got it prime stable now at 293 x 9... Why isn't it stable if the ram is 1:1? I know that the ram is memtest stable up to 305...I've tested it personally...so what's going on? I tried more vcore...I tried more vdimm...more chipset...

Now I'm starting to think that maybe it's the psu not being able to supply both the fsb and ram with enough voltage? but I want to rule out other things first... Thanks for the help guys.

Hmmm with a 600 watt ultra, I think its safe to rule out the PSU.
I would think it is your ram, try a different multiplier maybe so its more then 200 but not 300 lol, do you really need your ram cranked up to 300? try around 250 and see maybe it passes memtest but isn't bootable at 300.

I want it cranked up to 300...because I paid about 300 bucks to run it that fast lmao... It's faster to have a high FSB and low multi...I just want fast. Fast is good. The ram is stable all the way up to 305...and boots into windows at most multipliers...just isn't prime stable.

EDIT: Be back soon...I'll try a smaller divider.

What timings are you running upto DDR600?
Maybe you should leave it to burn in overnight using Memtest test 8 and then try running prime/occt

Hmmm I would aslo try changing the other multiplier.. It's name seems to escape me at this moment if you want I will go to my bios and find what its called but it goes for 1x to 5x try it at 4x or 3x even at 300fsb.

Naw...not that. The LDT multi is at 3x...so it's not that...

I am upping the divider now to see how far the ram can go up to...


PS - The guy who asked about timings... at 305Mhz I can run 2.4-4-3-6 through memtest without errors.

EDIT: Actually I just looked and it was running fine at 4x? lol...totally stable at 293 x4? holy ****! I lowered it to 3 though just to get it out of the way...

I tried booting up at DDR360 divider...but it didn't even "verify dmi pool data" or wahtever...so I put it on ddr333 so how the ram is funning at what it was before almost 239 2-3-3-6. If this works I'm going to try to go up one more divider and loosen the timings to my 305 Mhz timings...maybe that'll work out? Let's hope!

Well the smaller divider didn't work...so here's the progress

FSB = 293
Ram = 239.8
CPU = 2637

I don't know what's going on...as soon as I go over 240 at this cpu frequency it's done...nothing...:-(

It's 623-3...

You think that by having the ram in the yellow slots that would do it? even if the ram is stable?

EDIT: I'm really clueless here guys...
