So I was debating on cpu's E6550 or E6750 so I decided on the E6750... Now this will be running on P5K Deluxe as in my sig... the ram will be upgraded down the road to ddr 2 800 or higher... What kinda temps would I expect on this from stock... to overclocked my "goal" would be 3.4ghz min... I still have reading to do but assume this is possible? I guess even if I had to settle with 3 ghz I'd be happy as well... I just wanted a rough idea what to expect temps wise...

Thanks

I just overclocked today a little bit.
3.4 is possible but not with the stock hsf I think.
My temps arent that good, I have only a mild overclock with the stock hsf.
At 2.88ghz right now and it's around 22 C idle and 40-45 when running orthos.
Running at default 1.35v.

Thats not to bad.. I plain to upgrade the HSF as well ... my buddy just got a E6420 and when he runs orthos his cpu maxes at 82... to me that sounds abit high for stock speeds...

I will be running the same ram as you do or higher... Just waiting for a price back... what does ur ram speed jump up to at 2.88ghz?

840. My motherboard configured the ram at 5-5-5-18 on 1.8v but the info specs for them say 4-4-4-12 at 2.2 so I set them at that. Running fine, I ran orthos for 5 hours, everything is stable.
Superpi takes 16s. Was 17 stock.

What are you using to read those temperatures? I don't think readings from programs like Core Temp are not accurate with G0s.

Core Temp. Is there anything else? Bios does show reading a bit higher.

Yeah I just finished a friend's WC rig and CoreTemp picked up 10°C idle temperatures on the E6750 which we all know is impossible. The room was at around 23°C. I am not sure what is best at this point.

Idle 35C

3.6 Ghz
450X8 multiplier
450 bus

Runs cool with the fans turned all the way down.

Super PI in 13 to 14 seconds.

Tell your friend to try remounting, and perhaps using some AS5...$5 isn't a big investment. Also try lowering the Vcore especially if he's running stock speeds. Even w/ the stock cooler that is way too hot, and can be fixed easily.

Most people on here are using CoreTemp w/o issues. It either works or crashes on most people's rigs. What version are you using?

You should be able to get into the 3's pretty easily even on stock cooling if you mount well w/ AS5, and undervolt a little. With a good HSF you should be able to hit 3.4+ pretty easily.

I don't know a whole lot about that particular RAM you have, but if it is D9 based you may not need anything new. It may OC to DDR2-800 speeds, or even DDR2-1000 (this would put your CPU at 4GHz if you run 1:1) speeds. See what it can do when you loosen the timings before you upgrade.

If you need to get new stuff Crucial Ballistix DDR2-800 has had a good MIR (~$80 AR for 2GB) for a while and will easily do DDR2-1066 speeds, and may even go up to DDR2-1200 speeds when the timings are loosened.

Yeah I will see what I can get first with my current ram...On my highest oc without going 1:1 was like 3.9ghz or so.. and ram was running about 753mhz running 5-5-5-15 timmings... and stock voltage... I am hoping to get the new cpu in the next couple days....

As for Crucual here it seems to be about 140-150ish was a couple quotes I got for 2 gig kit @ ddr2-800....

No, what I'm saying is the temperatures are unbelievably low. I don't think a new stepping could drop the temperatures by upwards of 20-30 degrees. Did the tjunction change for the new stepping?

The crash is fixed in the next version, if anyone needs it they should email the creator he'll gladly give it to them ahead of time. Gave it to me, it fixed the problem. It says it supports C2D but the temps from it do seem lower....bios reads about 5C above Core temp on idle.
What else can I get to see my CPU temp then? I'm concerned now lol.

Jason, I'm new to OC'ing but don't you usually need to up voltage and not lower it to get higher speeds? What do you mean undervolt?

As far as I know people were using CoreTemp specifically b/c the new steppings (G0) were giving problems in other programs. TAT should work too, though.

I don't know why it wasn't working for you. Which version was it?

Yeah, to reach your max OC you may need to raise your voltage, but if you raise it too early temps may hold you back. If you're using a stock cooler I've found I was actually able to get a higher OC by lowering the voltage a little. With stock volts my temps were just too high, and by lowering them I was able to raise the FSB a little more, and still have load temps in the upper 50's/lower 60's. It's all a balancing act.

I wouldn't worry about the BIOS being 5C higher than CoreTemp. I don't know why the BIOS would work the CPU harder than idle, but I've noticed the same thing before as well. CoreTemp & TAT are the best we have right now.

I was using .95. TAT gave the same temperature readings that Core Temp did.

Well which is it? London or Ontario? J/k! :beer:

I don't know if you can get the same deals we can get in the states, but I know most people on here recommend the Crucial Ballistix, and G.Skill HZ's. Check out the Memory sub-forum for some other good D9's. Someone may be able to help that knows the Canadian market better.

Just google Intel TAT. It stands for Thermal Analysis Tool.

Well at least they're consistent!

I'm not sure what your problem could be then. Maybe start a new thread about this. I haven't heard of this issue before.

No no. I think you are misunderstanding me. I am not only questioning my own readings but everyone else's. I don't believe you can run an E6750 at 1.48 vcore on air and only be at 47°C fully loaded. Unless that person cheated? :confused:

Cool thanks. It's showing about the same temps are core temp, 1-2 C higher on idle, almost exactly the same on load.

Well I know the G0's run cooler than previous steppings...even w/ similar voltage. I know the quads are running very hot w/ less than 1.4v, but the duos seem to be able to take more. At least that's what I've been reading. Some will argue the U-120-X is as good as some water cooling set-ups. I'll know more for sure in a couple days when my e6750 arrives.

Which specific thread/post are you referring to? Are everyone's results like that?

If they were getting too hot they would throttle down, and that would be noticeable.

Something is definitely wrong here, though. You can't be below ambient unless you have some kind of chiller in the loop.

I haven't seen any other posts where idle (CoreTemp or TAT) is below ambient, though. Even at stock freq. w/ extreme undervolting, and lapped CPU & HS.
