E6750 + Tuniq Tower 120 - running too hot? New Tjunction.

you need to run memtest. did you relax mem timings to auto and run mem at 2.2v as recommended by crucial while overclocking? remember that memory timings are much less important to overall system speed on a c2d than actual cpu mhz. at 450x8 with auto mem settings you shouldn't have any problems with 4x1 gb ballistix.

But that's the thing.

There DEFINETLY is a problem. And not only with my system, but friend with different mobo has similar issue with his RAMs as well. 2x 1GB ballistix + 2x 1000MHz Mushkin.

With 4x1GB he got only 856MHz out of the RAMs with 4-4-4-12 and 890MHz with 5-5-5-15 (or so called auto settings).

Since 32bit Vista won't can't issue more than total 4GB of RAM + SWAP count together and you even have to reduce your video card RAM from that (since it's addressed specifically in Vista and takes room) - Im left with 3.25GB if I've 4x 1GB sticks and this 640MB RAM 8800 GTS.

But yes, I tried 5-5-5-15 (and rest by the default) and 2.2V voltages. I also tried upping GCH by 0.1V. It did not help.

Im currently running FSB435 with 2 GB, after 8 hour torture test (prime) system seems stable, temps peaking at 65C'. Im fine with this. 🙂

that's great, but what's the point in paying for 4gb if you can only use 2?

Well there kinda isn't any idea buying 4x sticks. If you want 4GB, buy 2x 2GB so you can be sure it works flawlessly.
 
Your temps are fine.

One thing i've given up on is trying to explain here is that temps can vary a ton depending on ambient temps (enormous factor actually), case airflow, & CPU (e.g, one E6750 could idle 5C higher than the next one, with the same vcore etc.).

My CPU can idle @ 30C - 55C, purely depending on my ambient temps (no, i am not kidding). Of course, by most standards here, i'd be told that z0mg, i'm killing my CPU by allowing it to idle @ 50C, which is utter bullshit.

But people here are too blind to see that, so i've given up replying to temps threads.

I would try to keep load temps below 80C, as IIRC, throttling occurs around 85C.

But running 70C under load is nothing to worry about.

I've tested a number of OEM systems w/ their stock or nearly stock cooling, & they often run hotter at stock speeds than we run our CPUs OCed with a lot more vcore.
 
actually, I've heard of many problems from people running 2x2 as well. Maybe Gary Key will weigh in on this one, I seem to remember hearing him say something about that a couple of months ago.
 
2x2 GB Mushkin ftw.
Unfotunately AFAIK, no other manufacturers have any decent 2x2 kits yet other than Mushkin, which while good for Mushkin, is bad for prices.

And Pride, you should be able to get 4x1 GB running fine.

No, it won't OC as far, & you might have to increase NB voltage, & possibly vdimm, or possibly loosen timings, but it can be done.

Granted, if you're running XP, there's not a lot of benefit to that, but if you run Vista, it's well worth sacrificing RAM speed to have more 🙂
 
I think what is confusing people is the distinction between what normal idle safe temps for a CPU and what normal idle temps are expected with certain coolers. Of course, N7 is correct saying ambient temp is a huge factor.

Now when somebody has equipment like Pride and is running 52-55C at idle with ambient temp at 23-27C there is a definitely a problem there. Probably a poor HS mounting job or something else. Now that doesn't mean those temps are killing your CPU. It just means the HS is not doing it's job or there is something else going on.
 
Pride,

What kind of Thermal paste are you using on that Tower?

I found Artic Silver 5 makes a HUGE difference, to the tune of 5 - 10C lower temps.

Im using the one that came with Tuniq Tower. Really thick, grey, stuff 😛
 
I built the computer from scratch now.

Re-attached Tuniq Tower myself and it seems that the morons that put it together, attached the fan wrong way.

Running FSB430 now (3.44GHz) with VCore 1.4V, peaking 66C'. Much better than the 81C'. 😀

Im thinking I won't up the VCore from 1.4V, guess it's just time to find the FSB limit for 1.4V.

Thanks for your reply.

I noticed a HUGE speed difference in start up when I've 3x 1GB vs 2x 1GB, so Im definetly keeping at least 3GB in.

Short memtest86+ testing showed that 3GB can be run @ 960MHz, 4-4-4-12 @ 2.2V and that's enough for me. Problem is, upping FSB means I need to lower multiplier so currently @ 860MHz.

Good job! I'm glad you figured that one out. The Tuniq is tricky that way. It really does not show you which way the fan blows. I installed it backwards also but I had the sense of mind to check and make sure which way it was blowing. 🙂
