Could my problem (BSOD 124) be VCCIN rather than VID?

What is interesting / concerning is that I've played countless hours of FC3 with the same settings for months. Now all of a sudden I'm getting BSODs with those settings.

I would bump your VCCIN (eventual input voltage on your board) to 1.9v. That is totally safe, see if your stable and then you can lower it from there if you want to. I've run mine for several months at 2.1v with no problems.

If you VCCIN is too low, it really doesn't matter what you do with vcore you'll still crash.

thanks.

just want to ask
I enable SpeedStep in the bios and features from 8x to 45x normal but Vcore always showed the highest position does not fall following SpeedStep.
It's normal on OC Condition or something missing? biggrin.gif

Since it has not been mentioned, you need cpu-z 1.64.0 to show you vcore correctly - hwinfo will too, and is probably better, but make sure to look at the "Vcore" sensor, and not VID!

With c-states etc enabled and balanced power plan, it will drop and show tiny volts @ idle, or even float around ~2ghz/0.7v on the sensors when doing stuff like web browsing

BSOD x124 I believe is related to an unstable uncore frequency vcore will not solve the issue

increase ring voltage or decrease ring multiplier (uncore ratio)

make sure vccin is set for 2.1-2.2V. drop this voltage if you can once stable ring voltage and frequency is attained.



I run my VCCIN at 2.2V on both a 4670k and 4770k for almost a year...no issues both at 4400MHz uncore frequency

All my 124 bsods have been vcore related. FWIW.

Both uncore and lack of vcore can throw 124 - my standard procedure is just set uncore 33x@1.15v until you can be sure that core is not throwing it, then OC uncore afterwards

See I rather try for 1:1 and then drop uncore as necessary. But that's the beauty of this hobby, we can all have different methods for more people to try.

I try for 1:1 too, as much as it makes sense (it doesn't affect most of my benches so i don't use it on 47x, but i do for lower oc) but if you raise both at the same time and get a 124 thrown, you have no choice but to guess why that 124 happened.

If you go from 35/33 to 45/33 and get a 124, you can raise vcore. When 124 no longer happens, you can raise uncore to match - and if you immediately get 124's, you can know for certain that it was caused by changing the uncore multiplier with those voltages

I ordered one from them when they were on sale last week. 359 Malaysia batch, and it's shaping up pretty well. I'm still tinkering with it, but I should be able to lock it in at 45 multi and 1.215 Vid without temps getting too crazy (I can do 46 multi @ 1.3V, but temps hit mid 90s in Prime). Once I get it under water, I'm gonna open it up and see what it can do. I'll report back once I get my uncore and other extras dialed in.

Edit: Sorry, it was batch 345. Don't know where I got 359 from.

hey just curious how your system scores on cinebench r15 at your 4.7OC

I typically hit around 955.

47core \ 44 uncore

I hit 950 with 46x/40x and my RAM at worse settings than it's at now (2200 9-10-12-20, 104trfc sammies)

Too many people bench differently, some use safemode, others just realtime priority, it depends how much stuff is running on your system etc. I think 4.7/4.4 was in the low to mid 970's, but i never really tested it because i was never stable and cool enough to use 4.7 with HT 24/7.
