Over the weekend had a play with new Gigabyte X79-UD5 motherboard with retail Core i7 3930K 3133B464 batch Sandy Bridge-E cpu. Gigabyte X79-UD5 board photos here.

The Gigabyte X79-UD5 shipped with F3 bios, but I immediately flashed the main bios (dual bios) to F5d. Unfortunately, I think the bios still needs work as I tried every setting available and can't get Load Line Calibration (LLC) to work as I always get around 0.048v to 0.06v droop under load, so not sure how that affects my max possible overclocks ? Here's hoping more mature bios updates come

I don't have any Quad Channel X79 memory right now so can't take full advantage of the Gigabyte X79-UD5 and 8 dimm slot support. So decided for first attempt at Quad Channel on X79, I'll use 4x 2GB A-Data 2000X 9-9-9-24 1.6-1.8v rated Elpida BBSE based memory which consists of 2 sets of 2x2GB dual channel kits.

System config:

• Core i7 3930K 3133B464 Sandy Bridge-E
• EK Supreme LT H20 with Fesser 480 Rad
• Gigabyte X79-UD5 F5d bios
• 4x 2GB A-Data 2000X Elpida BBSE
• 2x HIS HD3850 CrossFire
• 60GB G.Skill Phoenix Pro SSD
• 1200W Silverstone OP1200 PSU
• Additional cooling: 180mm Silverstone fan + 140mm Xigmatech fan
• WinXP Pro SP3 32bit (cpuz not detecting all 4GB nor is it detecting SPD for memory ??)

Quick 12x 16M HyperPi and Super Pi 32M with Aida64 (bandwidth report seems to be off ?)

All done with 1866 mem ratio with 4x2GB A-Data 2000X @7-9-8-25 1T timings.

Some 3Dmark was done with 2x GB G.Skill 17600CL7D-4GBPIS 2200Mhz 7-10-10-28 PSC based memory earlier on in dual channel mode (only got 2 sticks)

single HIS HD3850 at stock



2x HD3850 CF runs at 4800Mhz at 1.500v idle and 1.440v load

3dmark2001 seems to be 3930K's weakness performance wise ?



More testing to be done with hopefully more mature Gigabyte X79-UD5 bioses. Hopefully, get some memory manufacturer samples after Xmas for proper Quad Channel testing as well.

Very interesting results... SuperPI seems fast... While memory benchmarks are low... Odd... C-States enabled or disabled?

Anyway, thanks for finding time to test, but... no Hypers action?
