Poor Overclocking on Pentium D 930?

[Jamsan]

Hey guys,

I recently bought a Pentium D 930, and it is seriously a joke of an overclocker. I dropped it in to the same rig I had my p4 630 running at 3.9 stable on air, so the D is kind of a surprise to me...Right now, I'm only running stable at around 3.31. My load temp (dual primes + 3dmark) is around 52C, so I think i have a little headroom there.. I'm running stock voltages on the CPU, but even if I go as far as 1.450, it still isn't stable, and usually reboots as soon as the XP splash screen hits, or as soon as i start to do something once in Windows.. Am I doing something wrong? Is the rest of my system holding it back, or did I just get a bad chip? I also recently flashed my bios to the latest release from Asus to support the p4 d's.. could that be it?

Rest of specs:
-Asus P5LD2
-2GB GeIL PC4300 DDR2 3-3-3-8
-Enermax Whisper II 535w PS
-7800GTX
-3 harddrives, and 4 fans.

Could it be a power supply issue? Thanks for all the insight

I think you just ran into the mysterious ~225mhz fsb limit. I think theres only one board so far thats been able to take the Preslers over 225...

Which board is that? (time to upgrade )

Try the P5WD2-P.....

Mine is a refurb that I picked-up on Newegg for $140.00.. It seems the price went up $10.00 since then. Now $150.94 + $1.00 Shipping.

Do you think it'd be worth it to get a new one for $30 more?

To me.... No. I expected a bare mobo with no accessories to keep my upgrade cost lower. It would have been nice if at least the I/O plate was included though...

If you have the $$ to spare, a new one may not be a bad thing....

New one it is -- Anyone wanna buy a P4 630 and P5LD2 :-D

also -- do you think I should pick up some new ram? I have 4 sticks of 512 (2 1gb dual channel kits) of this herehere -- I'm only look to hit 4 gigs as I only have air cooling (xp-120)... do you think this would hit it without a problem? and if not, any reccomendations on good ram?

There is a trick to those motherboards aparently, try setting your PCIe frequency to 110mhz, that allowed my P5LD2-VM to get to 245mhz FSB..

EDIT: oh, and I wouldn't push for 1.45v either, since I'm not sure if thats what killed the second core on my first 920..

Hey Jamsan, you may want to wait a week or so before pulling the trigger on the P5WD2-P.... From a new post.... Here

We did preview the series here - http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2578

I do have a board under $100 running our new 950D at 4.8GHz in testing right now.

Gary Key will not disclose which mobo this is until the review is up. (another week or so) Who knows... it may be worth the wait.
