Hi all, sorry if ive posted this topic in the wrong area :?

Ive just upgraded to a Intel Core 2 DUO E6600 cpu, in the BIOS its telling me that the cpu is only running at 1.8Ghz is this right?

Its also rebooting and logging an "NV" error in the event log, ive searched for info on google and found that it might be down to my RAM?

Any help/advice you can give would be great

Spec

Core 2 DUO E6600 cpu
2 x 512mb TwinMOS PC2700
Nvidia 6800 GT
Hiper Type R 580W PSU
Hitachi Deskstar 80GB SATA disk

Hi,

Can you tell me what motherboard you are using?

I'm just wondering:

1. Why r u using PC2700 RAM while PC6400s are not expensive at all now? As far as I know, PC2700 is DDR333 and C2D E6600 needs DDR2 (At least PC5300). Recommend: 2x1GB PC6400 (DDR2-800) RAM CL4. Correct me if I'm wrong.

2. Why r u using a 6800GT while u r using such a good CPU? I guess you want to hold on this card and upgrade very soon to a DX 10 card, right?

3. Ur PSU is too powerful for ur current build, unless u will add a DX 10 card soon.

Personally, I think your problem is your RAM, and your FSB is only 800 while 1066 is standard.

Your RAM and mobo are holding you back.

I needed to keep the cost down, as iv got a new car coming next month so ive not got much spare cash.

Motherboard -> ASRock 775I65G R2.0

Im using PC2700 because Ive carried it over from my old system and this board is the only one I could find that still has a AGP port but it doesn’t support DDR2, I’ll have to try and get some Corsair PC3200

You are using 865G chipset based motherboard, which only supports
upto FSB800. that's why your processor is running at 9*200 = 1.8 GHz.
Your only choice with this motherboard is to over clock the FSB to 1066
to run the cpu at stock.

ok that not a problem i dont mind overclocking it, what should I set the FSB to ( 245? )
March 2, 2007 12:09:11 PM

266

Ok cool ill give that a go when I get home tonight :D 

Cheers for the help

I disagree :p 

i use a pc2700 memory with my e6600 just cause i had it and i couldnt be bothered to spend another 130 to get 2 gigs again. My cpu runs just fine on my asrock 775 dual vsta board at 2.4 ghz

did you have to overclock your cpu to get it to run at 2.4Ghz Blade85?
March 2, 2007 3:25:06 PM

Err...Why bother with E6600 when you're on a budget? Geezus you could easily grab a E4300 (~$170) or a E6300 (~$180) with a Gigabyte P965 DS3 motherboard (~$130) for the same price as the E6600 and overclock it to 2.2GHz for similar performance. Add 1GB DDR2 667 (2x512) for about $80.

Every thing else you have in your setup will hold back the power of your CPU. It'll run ok, but you just wasted your money.

Not only that, your computer setup is pretty much outdated even with the CPU "upgrade."

The only money I have wasted mate is £30 on the motherboard!, this setup has got me up and running again until next year when I can afford to upgrade fully using the E6600 cpu at a base with SLI cards!

I've upped the bus speed to 266 and the processor is now running at 2.4Ghz :D 

Ive also fixed the rebooting/infinite loop problem by using an older version of the nvidia drivers :p

Not sure about the NV error, but about the E6600 speed, I think that would be due to the speed step settings.

The bios should have settings for that, as well as windows under power options. Those settings help conserve on power consumption.

Chances are if you put that CPU under load, it should go back to normal speed.

Under the FAQ in CPU-Z website:

Quote:
Q: CPU-Z reports my CPU speed below its stock frequency.
A: This is the effect of C1E (Enhanced Halt State) and/or EIST (Enhanced Intel SpeedStep Technology). Load your system and you will see the frequency increase to its nominal value.


Hope that helps.
