Gigabyte X48T DQ6 Living Review

[supershanks]

It may be a number of things driver issue etc., However you need t remember that Prime etc., are in effect a measure of probability that the system is stable. This doesn't exclude that an error may occur, just that the probability is lower.
I once forgot & left my pc priming while I was on holiday:-

So it failed after 94hrs , is it stable ??

I think

Run at Turbo or standard, extreme is the fastest, but also the most unstable.
I'd also try

may help you Turbo should do it I think.

My cores usually running prime are pretty close to each other. You may find that running with a better cooler may cure this. It's also possible to get a temperature sensor that's sticky, not as sensitive as the other. see if it persists with your new cooler.

i think its a world record i dont now if somenone failed at orthos after 94+ hours!maybe prime95+ helps for a 95+ hours error!and yes its stable veeeeeeeeery stable

Yes , that's my point the test is a probablity test, it doesnt preclude a lower risk of error, Just that the odds lengthen

Hiya,

So glad I found this forum and thread about my own mainboard here! It's immensely thorough.

I'm trying hard to make my system as cool, stable and mostly quiet as possible. There are several websites specializing in that, but I found that this (my) X48T-DQ6 can't handle most of their recommended heatsinks without me having to remove CrazyCool parts from my board, which I don't want to do.

Here's a nice listing of coolers and their noise:
Lautstärke : CPU-Kühlercharts 2008 - IV: Was taugt Frischware?
and of course there are:
Recommended Heatsinks | silentpcreview.com
and
Recommended Fans | silentpcreview.com

My case is really big (a Lian Li 2010B), so they all fit, but it seems the CrazyCool is often in the way. Thermalright coolers all say they're not very compatible if you don't like removing the copper from the board.

Most sites are unclear on if the removal of CrazyCool parts is only required during montage/installation, or if it is permanently off the board.

It seems some here have experience using the Xigmatek HDT-S1283 CPU-heatsink. They don't have a 'Motherboard compatibility' listing on their site, so I just don't know. Are there any pictures of people having the S1283 installed on their X48T ?

Any and all insight and experience with this is highly appreciated.

(I will update my system specs shortly)

hi Meowbay,
welcome to the forum
Not sure why you want to keep the crazy cool it's easy to remove or replace see Removing CrazyCool Heatsink. I'm not that certain what extra cooling it brings. The fact that it's discontinued in the revised board maybe implies gigabyte think the same . I've run the motherboard with the crazycool removed.
the Xigmatek has a few things going for it:-
1) it mounts with pushpins, unlike the thermalright's which need a backplate. So shouldn't interfere with the crazycool. Personally I don't like pushpins, but here it would be an advantage.
2) The rubber fan mountings & fan are very quite & efficient.
See Frontpage for a variety of Xigmatek Coolers

The minireview I did Xigmatek HDT S1283 CPU Cooler was done with the x48 board fitting wasn't an issue , but it was done with the crazycool removed as I used a backplate.

Oh I'm sorry, I thought the entire copper thing was called 'CrazyCool'. If it's just the backplate thingy I'm fine with it.

I got my 'problematic thought-pattern' ;-) from here:
Ultimate CPU Cooling Solutions! USA
When you click on 'Compatibility' and then see the removal instructions for the X48T, it looks like they remove the entire copper-cooling from the surface of the board.. Can you assure me that's not the case? Because then I will go with a Thermalright Ultra-120 eXtreme

no thr carzycool , is just the plate underneath the mobo. Why should thermalright's suggestion be more calid than
a) gigabyte's
b) our explanation

vCan you assure me that's not the case? Because then I will go with a Thermalright Ultra-120 eXtreme

I wouldn't get the Thermalright a I intimated in earlier post. Save yourself some money & llok at XIGMATEK

thanks for sharing those Meowbay looks pretty decent stuff that

just for the history i mailed to gigabyte service about x48t and the gtlref1 and 2 defaults and their answer was :the default voltage for gtlref1 is 64%; and for gtlref2 is 67%.
