Just finished setting up my new rig. Remember when we were wondering whether the E6x50 series were giving wrong core temperature?

Well, I didn't have time to test it fully yet but it looks like some apps are giving inaccurate temp.

On my E6750 + stock heatsink + GA-P35-DS3:
Core temp (v0.94) at load (orthos) : 43'c
Easytune5 at load (orthos) : 49'c

The Easytune5 app came with the mobo. It is consistently registering 6'c higher than core temp.

I remember irenic's E6850 giving a load temp of 51'c at 4.0Ghz (stock heatsink) which I thought a bit too low.

Anybody can confirm this? What CPU temp monitoring apps are you all using for the E6x50 series? Wanna get the core temperature correct first before I start to overclock this baby.....

Going to test with other apps (e.g. speedfan) tomorrow after work......

That's what I mean..... core1 at 19'c??!??


Errr.... can you clarify that? How can it be accurate when there is a 9'c difference?


No necessarily as Rightmark CPU clock showed 6'c higher than easytuner5 which is 6'c higher than core temp!!

I guess I still have to wait for newer apps that truly support these procs and will show the correct temp......

Those with E6750, mind giving some feedback on your OC?

So far, at stock 1.35v, I'm able to boot at 3280Mhz and also orthos stable.

Going to go for higher vcore later..... (anybody knows the safe voltage for running 24/7?)

You sure it is the CPU and not the mobo/ram? Intel's CPUs are supposed to be able to OC more than that! 3.0Ghz to 3.2Ghz only is strange.....

My E6750 can go from 2.66 to 3.28Ghz at stock voltages (1.35v). Haven't tried higher vcore yet....

What rams are you using? What's the vdimm? Try to set the rams to DDR2-667 speed.

I don't think you have to do anything to the voltages yet. Most of the time, you can OC the CPU without touching any voltages. It is only if you want to go higher, then you start to increase the voltages.

It is probably not your CPU, considering that you set the vcore to 1.6v. That's high!!!!

Me! Me! I can test your proc for you! But I'm in Kuching la...... difficult.... Or you want to exchange proc?

Yeah, same ram as mine. Wah, already set to 2.225v ka? For my rams, at 5-5-5-15, 2T at 2.0v, can already go up to 1150Mhz. So I don't think you need to set the ram vdimm so high at 800Mhz. I was actually running my rams at 4-4-4-12, 2T at 800Mhz at 1.8v. Now still finding out the limits for these nice rams.....

If you have been Ocing your previously proc, then I guess you know how to overclock......Anyway, not too sure why you can't OC your CPU. I'm also still new to C2D and still learning the proper way of overclocking C2D.

Ya, I didn't have time to OC further as I'm in Sibu now. Only had 1 day to play with my new rig. Can't wait to get back to kuching!!!

3.2Ghz is only at stock vcore. I have yet to increase the vcore.

Not much time to play with the rams too. Will test further when I get back. For me, I prefer every component to be stable, at least orthos and superPI stable.

Why not increase your Vdimm to 2.0v? I mean, these rams are rated at 2.2v max and warranty covers until that high anyway. I'm probably going to find a sweet spot for 2.0-2.1v vdimm.....

What are you talking about? You also have quad core ma.... some more just let your brother use the quad oni.....

Nice. However, I really wished forumers would also include important info such as vcore, vdimm, vMCH, vFSB, core temperature and type of cooling.

Here's mine doing stress test at stock 1.35v. Notice the supposedly CPU temp at 55'c on stock heatsink!!!

Don't dare increase the vcore until I get my new heatsink.

Quite a bad vdroop though, about 0.03v drop at full load (is this acceptable???)

See my stock NB temp at 41'c only....

Wah! So high settings! You could probably get better superPI if you tighten your ram timings.

See my modest OC on stock heatsink. Can't OC much until I get my xigmatek cooler.

My rams are also Crucial ballistix PC6400 running at 4-4-4-8, 2T, 2.1v at 960Mhz......

I don't think you need to increase your vMCH at all. My P35-DS3 can go up to a bus speed of 480mhz without any increase in vMCH or vFSB.... Can't go any higher probably due to my CPU FSB wall.....

Ya lo, if want higher OC on the bus speed, should migrate to P35. My Gigabyte P35-DS3 (value for money performance mobo) can OC to a bus speed of 480mhz without any voltages adjustment (either vMCH or vFSB)!!!!

Ooppsss, me using E6750 and P35-DS3 oni la.... so sorry, cannot give any advice.....

I have seen forumers recommending the abit IP35-E. As far as I know, this mobo doesn't come with full solid caps and only support DDR2-800 (this is the specs on their website). Take a look at their website to see the specs.

I still recommend the P35-DS3. I consider this mobo as a cheap value-for-money performance mobo. Full solid caps and supports DDR2-1066.

For my mobo, can overclock the bus speed to 480mhz without increasing the voltages!!!

Nice. What's your vcore?

How about core temp at load? What temperature monitoring software are you using?

Why is your DDR2 running at such loose timings?

All the new E6x50 series are G0 steppings. However, the best new G0 stepping seems to be the Q6600....

Yeah, it is known that 0.95 has some problems, usually causing BSOD or computer restart. Get the 0.95.4 as suggested, much more stable....

Errr.... how about DDR2??

Hehe, was just pulling your leg because your question was too general....

It depends on whether you want to OC your rams or not. If you want normal rams for normal usage, then value rams DDR2-667 2x1gb would be enough....

If you want performance rams, then the general advice is go for DDR2-800 2x1gb 4-4-4-12 timings.... However, this is only a general advice, the better way to look for OC rams are those with the following chipsets - micron D9 e.g. D9GKX or D9GMH....

In terms of brand, any well-known ram manufacturers are acceptable e.g. OCZ, corsair, crucial, patriot, etc. Personally, if you ask me, I would go for crucial ballistix rams, they are relatively cheaper for high-performance rams, acceptable quality, and great overclockers!!!
