Hello,
I am in the process of upgrading my system:
RIVE (bought brand new), BIOS 4004
3930K (also new in my system - bought used one, previous owner claims that he used it on RIVE as well with no OCing and with water cooling)
Patriot Viper 3 4x4GB 1600 CL9 (ran fine on my P8Z68 + 2600K)
HD6950 (as above)
Chieftec 750W PSU
CM HYPER 212 EVO
From the very start I was having strange issue with BSOD 0x00000124. Memory dumps analysis points to Windows Hardware Error related to GenuineIntel (CPU I assume). It is fully repeatable/recreatable issue which happens in the following conditions:
- put a high load on CPU (Prime95 but any other torture test is good)
- wait till CPU heats up (50 C deg is fine)
- stop the torture test
then PC crashes immediately with BSOD 124 😞
Sometimes just a regular Windows boot up causes this because CPU is loaded when Windows boots and when booting is finshed, CPU clock drops an bang ! - BSOD 124.
I read multiple threads related to BSOD 124 on S2011 and they say about VTT, VCCSA and VCORE voltages. Actually I performed endless number of tests, BIOS setting changes, Optimal defaults, Safe defaults, etc. etc. and the only setting that cures the problem is VCORE. Manual/Auto or Offset set to any value (positive or negative) does not help. But setting Manual voltage to a fixed value (such as 1.15V) seems to be a cure for this issue but then there is a side effect - VCORE is fixed and does not follow clock changes.
Why is this happening ???:
- faulty RIVE
- faulty CPU
- memory or something else ?
Any ideas ?
I also noticed some obvious bugs in the 4004 BIOS:
1. Turbo Clock set to Auto does not mean stock clocks ! It sets all cores to the same max value, equal to Turbo frequency (3.8GHz). So you are OCing with Auto. Is it supposed to work like this ? On P8Z68 Auto meant stock clocks. If you want stock clocks on RIVE (3.4GHz max, more - up to 3.8GHz only if not all cores are loaded), Turbo Clock must be set to "by Core" and all settings (1-core, 2-core, etc.) must be set to Auto. Weird.
2. Setting AI Tuner to Auto sets incorrect voltage to DRAM. Auto should mean JEDEC settings for RAM (it worked like this on P8Z68) and timings are set correctly but voltage is set too high to 1.65V which is not correct because JEDEC setting in SPD is 1.50V ! AI Tuner set to XMP works fine - it sets timings to XMP (not very different to 800MHz JEDEC indeed) and DRAM voltage to XMP value, which is also 1.50V.
Best regards.
