QPI/DRAM is too high !!!

I'm testing my 920 @ 4.31 with CPU v @ 1.36, QPI @ 1.3, PLL @ 1.84 and RAM @ 1.65.

I'll post a pic. later tonight hopefully !

Just for a heads up on the qpi voltage, i have the kingston 2,000mhz ram and on profile 2 it sets my qpi voltage to 1.7volts. And i called asus and kingston and they said it was fine as that what the board needed to be 100% stable.

[tistou77]

For me, vQPI is 1.50v in bios, 1.46v in Windows and read the bios

about my cold boot problems with the bios 1609, I passed the 1506 and problems solved

[Andrea deluxe]

in an italian forum more people have problem with southbridge temperature sensor.....

anyone have tryed to solve the problem whithout RMA?

rma is too long.....

[yiannit]

I'm unable to flash using the Ez flash utility. I keep getting "Unable to load this drive or directory!" error when i pick my flash drive from the list

Those volts are what are required to be able to run rams at 2000MHz... If i use XMP profile, then directly set it at 1.6v.

[Le Titi]

For me work very well with 1504.

[Salamndar]

My Motherboard will not boot with Bclk higher than 211 at all !

I tired QPI/DRAM at 1.45v and still no luck !

I really don't like the idea of paying what I had payed for this mobo and not getting what I've expected !!

Sure it´s not your CPU?
Mine can do 220 but that´s the wall.
WIth another CPU it couldn´t do more than 200.

[Salamndar]

I tried 2 CPUs on this mobo and seems to be hitting its maximum Bclk that low.

[Solarfall]

i got this board last weekend and i only today had some time to test the max base clock.
this is with air cooling still, i will test how far i can take it with watercooling and if it can handle subzero temps next

I'm sure you mean the particular board you have. When I go over 210 BCLK on mine I have the issue posted earlier with the first video card not showing video. I don't think Asus told you that it would reach a certain BCLK. Even if you tried two CPU's perhaps both could not reach higher.

Lots of different areas than it just being specifically the board.

[kpablo]

I were able to boot at 211 and at 220... with Bios 1504 and this 1639... imo, it just depend on the processor... just, i don't need that much and the voltage needing was just too much comparing with what i need for 4.2GHz.
Maybe when my country get cooler i'll try again... currently during the day the ambient temps are around 37C -_-

[Salamndar]

where do you live ?

[CryptiK]

It probably depends on your particular board and your CPU. I have run benches at 215 BCLK on air and both cards worked just fine, and using quite low voltages, I
have got 211 BCLK prime/linx stable. 211 is still relatively low, but it was easily achievable.

@ Solarfall - very nice, looking forward to what you can achieve with this board.

South America, in a country named Paraguay... right in the middle of S. America, no exit to seas either...

Freaking hot in this days... and still we did not have reached the summer...

[Sizmik]

I might be asking a bit much, but is it possible for some of you guys to post your settings ?

Kpablo - think you made an error there. You really can't be using 1.625v for CPU VCORE for just 4.2GHz with a gem 3849B CPU right?

[Kain XS]

Anyone has this batch: 3931A231 ?
Mine does 4ghz with 1.23v OCCT stable but can´t pass 217 BCLK.

That is very high for just 4.2GHz, I hope it's a typo.

@kpablo, we seem to be running the same CPU (as far as Batch #) and ram but I'm running 12Gb's.

I just got the second kit back from RMA and did some testing and found (at this time) that I can run at 7-7-7-20 Memtest stable @ 4.2GHz. What is interesting was I forgot to change from 1T to 2T before I tested.

So is this normal running 12Gb of ram at 1T? I'll test again once I update to the new Bios. I'm hoping to tighten up the timing a little more, something like 6-7-6-20....we shall see.

Fixed!

it's 1.2625v.

I don't know man... i just put 2T because i saw in Corsair Forums, the corsair representatives recommending to put 2T if you want to run at 2000MHz.
I should do some runs at 1T... but i totally forgot it to test it...
