Asus M3A79-T Deluxe

With my SB750 ASUS, I decided to stay with 3.2Ghz (1.375v) even though higher clocks are possible. For example, my external (non-mobo) temp sensor on mosfets was spiking to 55C on high overclocks and I was getting BSODs that were odd. I concluded that even though my cpu temp under water was 44-46C under very heavy load, that other chips on my mobo were too hot.

Regarding cpu tweak, I found about a 9-10c difference on idle and 4-5C on heavy load. I leave it off and see no difference or slight increase on benchmarks. I don't like heat for little gain.

Bummer about your retailer. I think you posted earlier that the guy was giving you odd vibes about ship dates?

my temps on water with C & Q disabled and CPU Tweak disabled are about 27ºc idle and about 38-40ºc load.

With the factory cooler I was getting about 41ºc idle and 57ºc load. This is at 1.425v 3.2 Ghz

Thanks for the comparison info guys, and yes I had been getting odd vibes from the retailer, it all sounded a bit dodgy, I finally (this week) got a refund of my money, although they sent me a cheque rather than refund the credit card I paid with, so I'm waiting for it to clear now. Hoping to order the mobo from another company early next week, after the cheque has cleared.

well i got it back to 3.1Ghz and it idle @35c can 69c @ load im testing right now for stableness, but why does it jump up 35c am i doing something wrong ?

Ok it just stopped on me what can i be doing wrong

Hmm your Load temps seem to be really high, which is odd as your idle temp seems fine. You've got a very high idle/load delta there.

Sounds like it could be a poorly mounted HSF, adequate at idle, but not getting a good enopugh contact to efficiently remove enough heat under higher load temps. Try re-mounting the HSF.

I've got a slightly similar problem with a 9850BE on the M2N32-SLI mobo, using a Arctic Cooling Freezer Extreme HSF. It was really difficult to install as the HSF wasn't quite clearing the chipset heatsink on the NB. So its not getting a really good contact, so my temps are higher than I expected to see.

Still safe enough under low load, and I'm only using it as a HTPC at the moment so its not being put under any heavy loads, and I'm going to swap the mobo out once I get a M3A79-T, so that the M3A32-MVP will replace the M2N32-SLI, so the AC Freezer Extreme should fit better and make better contact to work with the 9850BE then.

OT: As I'm typing this now, can anyone with the M3A79-T mobo tell me if the whole SATA OPtical Drive and SATA RAID problems have been fixed with SB750.

I know that when I installed on SB600, the only way I could get things to work was to swap my SATA Optical Drive with an IDE Optical Drive, no matter what I did I could not get Vista installed with a SATA Optical Drive when using SATA HDD's in RAID.
