Windows 7: Show Us Your Rig [4]

I'm really not sure. It has never bothered me. I just assumed if they put it there, you were supposed to use it. Not so, according to Asus. Assuming they know what they are talking about. I only connected the 8 pin and have had no problems so far.

Well just to add my 2cents, I had majour problems when I tried to overclock my cpu,untill I plugged in the extra 4pin, I didnt think it would be nesasarry cause it allready had a 8pin in, but it worked and overclocking isue solved. So I dont know why, all i can think of is rather have it and not need it, then need it and not have it. But for temps etc I dont think it matters

+1 for the 4pin eps not being needed on the V Formula, Its just for stability at higher cpu oc's. I bought the Ax 850 because it had the extra eps connector but to use it meant i would only be able to run 1 gpu. The extra eps use's one of the Pcie output connectors
As others have said, it's not a must to use it but it helps.

Were the standards not developed when CPU's were 150w, like P4's, and many, if not most are now 100w. I believe the 4 pin was actually for the 150w, no? In any case, I think the leads all combine to the same path, and are from the same rail of the PSU. Discuss

A Guy

I'll go along with that Bill. On many boards. like mine, which have a single 8-pin Extended Power Supply (EPS) plug, the instructions say one may use only a 4-pin connector.

I've got Core Temp up and running on my machine and, other than all the crapware it both tries to install and actually installs (which I promptly got rid of), it's exactly what I wanted (and it has pretty colors)! Thanks again! I'd rep you but the forum says I have to spread some around elsewhere first.

This is my understanding
Safe CPU Temperatures? running from 9C-24C is it too cold?
I have some reference buried somewhere. I have found it interesting that Intel seem to give Tcase (& power) as their spec limits.
I have personally found that Open Hardware Monitor is a good tool and it appears their temp readings are:
1) under my Nuvoton NCT6776F CPU Core Temp it gives the Tcase
2) under my Intel Core i7-2600K CPU Core Temps it gives Tcore

As a rule of thumb I think Tcore ~= Tcase +10c. I also think most of the temperatature monitor programs estimate Tcore. So in summary if the Tcore reading is near Tcase|max+10c then things are too hot.

My 2600k overclocked to 4.3G may nudge 65c Tcore but hovers around 55c Tcase and is well under the Tcase|max of 72.6c.

I stand to be corrected.

The Tcase max on mine is 72.6C, while TJmax is 101C. Tcase can't be read as I take it, it is the temp in the center of the Integrated Heat Sink (IHS).
One reference

Re: second EPS connector. My P9X79 WS has the 8 pin EPS connector and also a 4 pin Molex connector insted of the usual 4 pin connector. According to the manual (yes, I actually read those things), it's for when more power is needed when running three or more graphics card. I didn't know that it was optional since I'm going to be running only one GPU card until after I got the board so I had a Molex cable and connector ready before the MOBO arrived.

I guess we agree. The best measure of heat damage to PN junctions is Tcore and definitely Tjunction.
So Intel why is Tcase a useful measure in practical situations since it is generally estimated?
