saturday maybe, I have to ask him and make sure he's not using it.

What PCI-E voltage should I have? I am starting to wonder if that is the source of my GPU's load instability.

@blitz - If you tell me where I can find the voltage, I'll tell you.

@everyone else, does anyone have any idea what the Trfc ram timing does?

It is in everest ultimate for one. Under Computer > Sensor, look for "PCI Express."

tRC/tRFC were my holy grails to getting the Gigabyte to POST over a 254 HTT. Looser is better for stability.

Blitz, what is the voltage that Everest is displaying for your 3850?

Anqt, tRFC Timing: Row Refresh Cycle Timing. This determines the amount of cycles to refresh a row on a memory bank. If this is set too short it can cause corruption of data and if it is too high, it will cause a loss in performance, but increased stability.

Source: Memory Timings Explained.

Hope that helps!

According to Everest, PCI-E voltage is 1.2 V. I am trying 1.3 V now to see if that fixes anything.

And I have good news and bad news for the club. The bad:

Try as I might, my old silver lady will not get me into the 1 GHz OC Club. With Thlnk3r egging me on, I even tried an uncharacteristic 1.800 V VCore, a 3.000 V DDRV, and a 2.000 V NBV. Couple this with 2 GB of RAM running at 3-5-5-10 running at DDR 386, and you still cannot make it POST.

The good news, I finally broke 30s in SuperPi. I was fiddling for the highest OC I could get that would run SuperPi. Any OC higher than this either crashes or runs OC super-30s.

As you can see below, I am running an uncharacteristic voltage for me of nearly 1.6 V:


The CPU-Z validation link

Needless to say I was flabbergasted at me finally breaking (significantly) over 3.0 GHz, as my Gigabyte could just barely squeak by.

This got me curious. Could I replicate the feat with four DIMMs of RAM instead of two? As Joe always says, "Testing, testing, testing!" So, I dropped those DIMMs back in and fired her back up. What would you know?


The CPU-Z validation link

Needless to say I am elated to see that she could do it. Temps idle were 45/50º C. Running SuperPi, about 51/54º C.

Right now, I have dropped my VCore back to 1.380 V, and am resuming experimentation to get my new S&M/24-7 stable settings going. Since I know that the RAM will never run at DDR 500 with four DIMMs (but apparently DDR 444 is not unheard of) I am going for tighter timings instead. I am running sub-SPD timings of 2-3-2-6-2T-11-17 @ DDR 401, 2.82 V to see what will become of it.

oh my god. 1.58v. lol lucky with low ambient temps. would never work in vegas. lol

1.540 V with four DIMMs. Same BIOS setting, but you can see a bigger droop.

Whats interesting with either is that the BIOS is set to 1.525 V.

For the record, ambients are 22.2º C.

More good news and bad news:

The good: My GA-K8NSC-939 has returned from RMA
The bad: They apparently destroyed my factory motherboard box; it came home in a GA-K8NS-Ultra box
The good: The board appears to be working again; as does my San Diego
The outstanding: I cannot, for the life of me, get this chip above 40º C
The atomic-failure: The processor will not POST at anything more than 2400 MHz. Yes, even at 1.600 V (max for my board if I remember right)
