Review of GIGABYTE's 2nd Gen. X79 Workstation MB: X79S-UP5 - Page 30

post #291 of 367
HCI gives an error after running for 7 hours, so the problem remains in the ram area. I'll probably just remove 32 GB this weekend and see if it is stable than. May add them later, when gigabyte finally discovers what's wrong with the board.

I know this has been a while and I'm using a slightly different motherboard, but I am suffering from low performance of my 3930K.

When I do a stock run with Intel Burn Test on High I get around 79-83 GFlops throughput. With LinX (the one linked earlier in the thread) I get around 100ish GFlops. When I overclock to 4Ghz I get up to around 88 GFlops in IBT and 115 GFlops with LinX. However that seems to be a sort of limit as I can OC all the way to 4.6 after that and the results barely change and in most cases lose about 1-3% performance over 4.0GHz.

Currently only using dual Channel RAM running 9-9-9-27 as my quad channel RAM proved to be faulty.

Running the UP4 board with F3t BIOS

Current BIOS Settings that are altered are:
CPU BClk @ 125MHz

Clock multiplier @ 36

CPU @ 4.5GHz

CPU vCore @ 1.365v

Turbo settings are set to same as base clock as turbo doesn't like the 1.25 gearing at all.



The results are similar if I use BClk @ 100MHz and just do multiplier and voltage increases, though admittedly slightly slower than the BClk method.

Will do a run at 4.3GHz tonight, but I've tested at 3.8 (stock), 3.875 (125Bclk), 4.0, 4.2, 4.25(125Bclk) and 4.5GHz (both 100 and 125 Bclk) settings so far. 4.0 to 4.5GHz though had no change in LinX GFlops results.

Will up a few screenies with next tests smile.gif

Reading thorough this thread and seeing how people have some complications with their overclocking, would they still recommend this board as I am currently offered a very good price and considering it. I'll be running this with a 3820 and would swap to Ivy-e when release with hope Gigabyte has done some fixing and upgrades to the bios for ivy-e.

Here's the results of testing at 4.3GHz with a BClk Gear Ratio set to 1.00 as well as a set at 4.25GHz with BClk Gear Ratio set to 1.25. Voltages were set at 1.28 vcore for both runs. It's also worth noting that the 4.3GHz run failed (which was just a multiplier OC) at 17mins into the LinX run hench no final pic for it.

4.3GHz Multiplier only OC


4.25GHz Multiplier + BClk OC

Tested in a GA-X79S-UP5 today. Got 137 GFlops in LinX with that CPU @ 4.3GHz and 1.295 vcore. UP4 just not up to the task by the looks of things. Wheres that RMA...

I am using the following settings in the BIOS:

LLC - Auto
Vcore - 1.34V (1.33V at load approximately which I think is good for 4.6GHz and 64GB of memory).
VTT - 1.2V
VCCSA (IMC) - 1.1V
DRAM - 1.6V (stock is 1.5V but I cannot get the system stable with 64GB at 1.5V; 32GB runs flawless though with only 1.5V)

DRAM timings - 9-10-9-27-2T



In my observations here is how the errors break down...

101, 0a, 9c - Vcore related
124 - VTT related
Hard-lock with no error code - VCCSA and DRAM voltage related

your gflops count is too low, are you running win7 sp1? if yes, then your cpu is definitely throttling heavily and not at 4.6ghz bro.

Late to the party much? lol tongue.gif It was long established that those settings were not stable, not the OC, rather the memory. The board cannot run 64GB of memory in an 8x8 config.

As a side note, bro, 64GB of memory and a 6C/6T (12T total) CPU will not see high GFlops even at 4.6GHz. I think that you need to learn first how LinX scales with different combinations and then you will be in a better position to comment on it wink.gif

I can verify that Dejanh, for some reason my PC has decided to play ball, now getting 135GFlops @ 4.0GHz (1.260v vcore)on 25000 problem size with LinX. If I do a full RAM run with LinX though it drops to about 115GFlops (80% of 16GB RAM). Also for the first time I'm getting higher LinX results than Intel Burn Test. I just wish this PC would make it's damn mind up about whether it wants to work or be crap!!!

Gonna test higher clocks though to see if there's any point to raising the temps wink.gif
