Vcore query

post #1 of 6
Thread Starter 
Gigabyte GA965-DS3 r3.3,
Ptm D presler 945 dual core 2 x 3.4ghz
OC 17 x 236bus, rated fsb 944 = 4012Mhz stable,
3 x 512mb pc5300 (333) @ ratio 2.50 = 295 Mhz 4:5 4 4 4 12
Cooling: Asus V-Nardo on CPU and a fan on NB heatsink,
Idle temp 44c


i need to up Vcore to run stable higher bus speed.

problem is: in bios Vcore is set to 1.33. Cpuz, Smartguardian and speeed fan show Vcore @ 1.248
if these progs are correct i have room to up Vcore before exceed spec sheet Vcore.
how can i be sure if bios or other progs are correct ?.

Also would my machine run faster if i used E6300, i know overal Mhz will be lower but is conroe going to give me a faster overall machine?.

There is probably a vdroop which means that the value that is set in your bios is a little higher than what you really get. so i would think that the programs are about correct but the only way to know for sure is to use a volt meter.

Preslers can do 250fsb on the stock Vc, mine does and I can get as high as 4.51ghz with 1.45v: http://valid.x86-secret.com/show_oc.php?id=110762

Nasgul yrs is the first 945 oc i found on a forum, this is my 1st oc, i assumed i could oc above 17 x 238 due to lack of vcore, it wont reboot if i do 238. i have corsair ram 5300 333 which is not oc so ram not the prob, if i go over 236 fsb reboot reports no "boot disk". i assume it not as easy as a real dual core (conroe) to oc.

Well, you may need to tweak a few settings, like for example lock the PCI-E to 105 and the PCI to 33.33mhz.

In my P5WD2-Premium, I can everything at stock and just by bumping the fsb to 250, then it boots to 4.20ghz fine.

You may also want to try to get a 1:1 ratio for that CPU/RAM.

And since that this is the first time I've ever heard about your CPU's HSF, it doesn't seem like it's good unfortunately: http://www.newegg.com/Product/Produc...82E16835101008

I have also a Tuniq Tower 120 in my Pentium D 945 and temps are great.
