UnOfficial EVGA X58 Classified Owners Thread

[Chillerzero]

There something wrong with your vtt-vdimm relation as cpu-z only shows 4GB of RAM, but triple channel. Is windows taskmanager also showing reduced memory size? If so, you have to adjust vtt a notch or two.

i got 3x 1gb dominator gt 2000Mhz cl7, in windows it show correct but only in CpuZ not .......

Okay, my bad. ^^

Hi guys,

Wondering if you can help me with my overclock. I have the 759 S227 Classified and bios. After setting a qpi of 195 to 200 (in e-leet) I get stop errors running Linx. It either aborts or I get a blue screen. My max core temps as reported by realtemp during Linx are between 62-67 (66-66-67-62) at 22 ambient temp. My cpu vcore at 1.3 vc with vdroop off and +200mv for cpu vtt. Ram at 1600mhz with 1.64 volts (stable at lower fsb frequencies so not my ram holding me back). Every thing else is set in bios at auto.

Wondering are my temps acceptable for water? My last stable qpi was 180. Seems stable there at 1.275 vcore. Have I hit a wall you think?

Thanks.

Which version of LinX are you using?

[davidm71]

Either the .63 or .64 version. Why is that important?

Hi,

Wondering what the fsb holes for the Classified are? I've been trying to reach 4.0ghz on a 920 D0 and had some difficulty after 190 bclk. So I was curious what my highest bclk for my board and lowered multiplier to 12 to take cpu out of equation and also reduced memory multiplier to 2:6 belowed 1600 spec (which works at 160x10). Then in E-leet slowly upped the clock frequency 5 mhz at a time. Eventually I got a BSOD around 187 (Error 3B) right after hitting the apply button in E-leet. I even tried raising the qpi pll and other voltages in eleet a couple notches and still got the BSOD. I also turned off vdoop, set cpu vtt +200, impedence to less and middle, cpu + vtt freqencies to 490/900. I'll fill out a proper template in a bit but my main question is does the Classified have fsb holes?

Hi,

I followed this guide on the evga site by upping the qpi 5-10 mhz at a time and reached a wall after 188 bclk where I would either get an error in Linx or blue screen. I tried raising cpu-vtt voltage, cpu vcore, then the other voltages listed below. Seems like once I crossed 188 bclk the system would not cooperate. I tried laxing the memory times without success even. My core temps never went over 60 degrees. Doesn't seem like my board can even reach 190.. Is it the cpu thats the limiting factor? Or the board? BTW I'm now running at 160x20 plus turbo with memory at 1600 stable but was hoping for more. May be able to do 3800 with lower memory frequency but it feels like its the board holding me back...

I have the same issue (except in my case the BCLK wall is at about 180), and have narrowed it down to a weak IMC on my chip. Try loosening MCH strap right out (doing this will reduce performance) - if you can lower the voltages required to stay stable by doing this or eke out a few more MHz, then you've got the same problem as me and nothing other than a new CPU will fix it.

[davidm71]

I don't understand how its the chip that is at fault because I lowered the cpu clock speed and ran the ram at a lower rated frequency.. doesn't make sense... Anyhow if thats the case I set up a water cooling system for nothing!

Thanks.

[cstkl1]

hmm actually raja explanation on i4mem on rtl and skews started making some sense now for me.

initial test only 2.1k 7-7-7-21.. stock subtiming for strap 1600

Whats the newest bios for the E760? thanks. Oh and off topic, what happened to the news section????

[FabricioGS]

It's the S61H. You can always get the lates bios from this topic on the oficial foruns: http://www.evga.com/forums/tm.aspx?m=13905

I assume you might be banned from it. If you cannot see it, that is.

In an i7 system, the memory controller is now on the CPU. As back in the days of FSB overclocking when you raised FSB you had to loosen out the NB strap to maintain stability, when you raise BCLK on an i7 system you similarly may run into stability issues with the MCH. On most CPUs this can be fixed by giving it more voltage (ie. raising uncore and possibly vPLL), but as with all things in overclocking, nothing is guaranteed and you may simply get a chip with an IMC that refuses to budge above a certain point.

The Classified is helpful here because unlike most X58 boards it lets you control MCH strap yourself, rather than working off of RAM speed (this, incidentally, is probably why lowering RAM speed isn't helping - if you leave MCH strap on auto I believe the Classy sets MCH strap in relation to RAM speed - meaning lower RAM speeds would give a tighter strap setting - although I'm not certain about this), so I'd suggest trying to loosen that out to see if it lets you raise BCLK a little higher. If it does, then unfortunately there's not really much you can do to work around it - at least as far as I know.

[Chillerzero]

indeed a lower MCH strap can help performance when you raise it it's for higher OC.

[davidm71]

Seems like you have more luck when you set your bclk in bios rather than using e-leet. I was setting it at 160 and failing stability around 185-90. Then reset the bclk in bios to 180, then to 200 and after a couple voltage tweaks it passed 20 runs of linx. Final 20x200 with 200x8 for the ram, 200x16 uncore, and 18x200 qpi frequency even though some have said that uncore to qpi ratio is not optimal for increased stability.... which I still don't understand why...

Will a Auzentech Forte card fit on the Classified in the PCI-E 1x slot?

It appears that the NB cooler will block a longer card (like the Forte) on the PCI-E 1x slot.

Hey guys, a quick question, my USB ports, all of them just disappeared while i was using the computer, i had to shut down and reset cmos to get it working again, anyone else experience this? is it normal or should i RMA? thanks.

This happened to me once but only once. I didn't have to reset cmos though I had to shut down and power down completely for it to come back. I think they may have a bios bug. Make sure your using the latest S227 Bios if you have the 759 like I do. The newer bios I heard is no good...
