Seem to have hit a wall. DS3 + E6300

Gibbs · 26 Sep 2006 at 12:01

Hey Guys, i have seem to have hit a wall on the O/c of my DS3 and E6300 C2D. Keeps rebooting after 5mins on 400x7, drop down to 390x7 and its sweet @ a stable 2.7Ghz

Now as you can see from the pic, my memory isnt running at its full speed, it is the GeiL DDR2 Dual Channel Kit (OcUK Product Code: MY-058-GL). Timings are 4-4-4-12 and that seems the lowest i can go. Plus its showing in CPU-z as 5300 wen its 6400 800Mhz kit.

Anyone anythoughts on were to go from here?

What voltages u running on fsb, mch, cpu, mem

Virdi · 26 Sep 2006 at 12:18

Please tell us your full system specs and post a pic of your bios settings

Also - What version of bios are you running?

Your RAM is also only rated to 333Mhz - So You need faster ram to start with.

Gigabyte GA 965P DS3 motherboard with F6 BIOS (CPU-z/Everest keeps saying its F3 for some reason)
Intel Core 2 E6300 at 390x7 resulting in 2.7Ghz
2 GB GeiL PC6400 DDR2 at 4-4-4-12
BFB Geforce 7600GT at 610/721

Voltage Ratings are in the above screenshot.

CPU Cooling?

...and why is your ram showing as PC5300 / 333..? if it's PC6400.?

Have you tried up'ing volts to 'VCore' and 'VDimm' .? Have you read the DS3 thread?

Gibbs · 26 Sep 2006 at 12:34

CPU Cooler isa CNPS9500 LED plus a 120mm fan blowing inbetween the cooler and gfx card cooling the NB, fan also cooling HD and SD.

upped the volts to the DIMM by +0.1v then +0.2v.

As am not sure to what am doing am not really pushing the RAM. Tips please?

wizardmaxx · 26 Sep 2006 at 12:39

That memory is meant to operate at 2.1v (+0.3v) afaik. Ive had mine up to 2.3v no problem so far. Ive tried aking on the forums for suggested fsb and mch voltages. No conclusive feedback on that though so running them at +0.2v. Dont know what max voltage would be for the 6300. Somebody could advise u there

Virdi · 26 Sep 2006 at 13:54

I am running 1.4750v through my e6300 and it's fine - My overclock is 495x7

As long as your temps are ok... it's safe to push up the VCore a little...

You should also push up you MCH and FSB Voltage to 0.10v

Gibbs · 27 Sep 2006 at 14:15

ill give upping the CPU voltage to 1.475 and then up the FSB

ill get back to you with the results

3Ghz Baby

Temps Stable at 36C Idle, will run a load test overnight.

I still need to sort out this RAM problem. PC5300 even shows on the valid test. What settings do i need to up in the BIOS and by how far to kick this RAM into 6400 speeds so i can push the o/c a little futher.

Cob · 27 Sep 2006 at 21:48

Mate your RAM's running at well over PC6400 speeds (858Mhz to be precise).

The Geil PC6400 identifies itself as PC5300 to make it more compatible out of the box ie- So it will boot at 1.8v rather than the 2.1v that PC6400 usually needs. A lot of boards are giving RAM only 1.8v at default(my DS3 included).

Gibbs · 27 Sep 2006 at 21:55

so the RAM is fine, sweet then. i was getting confused there.

So how does my clock stand so far? At 3184Mhz atm

Cob · 27 Sep 2006 at 22:30

It's looking good. My e6400 is only stable at 3280Mhz.

Gibbs · 27 Sep 2006 at 22:39

had to back of slighty to 444x7 to become stable at 3108Mhz

Cob · 27 Sep 2006 at 22:54

Did you slacken your RAM timings to see if the cpu would go any higher?

Gibbs · 27 Sep 2006 at 22:55

lowest i can go is 4-4-4-12 in the BIOS if i am thinking of what your thinking

Cob · 27 Sep 2006 at 22:58

Try 5-5-5-15 and see if she'll go much higher. If not, then drop back to where you are now.

What is your cpu voltage at?

Gibbs · 27 Sep 2006 at 23:09

v1.45 going to the CPU, wont take 1.475, keeps rebooting after hitting the windows desktop

Gibbs · 3 Oct 2006 at 01:11

3D Mark Score everything stable at 3.10Ghz and 610/800Mhz on the 7600 GT

not to shabby
