2500k Overclock BSOD #124 Question
2500k Overclock BSOD #124 Question
When the Q6600 was introduced I upgraded to the E8400, it became a powerful overclocker and seemed like the best decision for a while because few games or programs required more than half the cores. However, it soon lost its advantage when more multi-threaded applications appeared. My friend still keeps his Q6600 overclocked at 3.4Ghz since then, clearly lasting the test of time.
Prime95 Blend is currently running while I watch interwebs TV at 4.8ghz with a clock speed of 1.41v. Temperatures are between 58 and 63°C, and the fan is set to 60%. The new BIOS is functioning well, and I'm also using Offset Vcore, lowering it to 0.986v during idle. This should help extend the life of my 2500k processor.
Oddly enough the VID on my Chip was 1.36v - So when I put LLC to Ultra the Vcore jumped to 1.41v on max load - so I thought, thats stupidly high, lets try a 4.8ghz clock. As a result, Ive left the voltage on Auto for the CPU
😵
Offset is a strange one, but there is a nice thread on ROG Forums written by an ASUS rep explaining how to use it.
In Simple terms if you use Offset (-) it will drop both the load VCORE and the Idle VCORE by the same amount - leaving you with the issue of "Is my VCORE too low at idle" If you use Offset (+) it will increase your Load VCORE by the set amount but your Idle VCORE by only half that. Altering your base CPU Voltage can also help with the issue.
2 hours Prime Stable + Interwebs ( xD ) and counting.
I recall the VID of my 2600K being quite high too (at least 1.35V). I'll do some more research on offset voltage and see if I can get it to work. It's strange because it might stabilize with an offset under load, but it crashes sometimes when idle—no BSOD, just a PC restart.
2 hours is a good beginning; usually my overclocks fail within the first 20 minutes if they don't work.
Damn you, that really gets me going again!
I might try adjusting BLCK since I couldn't find the article about it.
Just pushed mine to 102.2 with a multiplier of 47. It’s evident my CPU/Mobo setup reacts well to a slight BLCK change and a lower multiplier for balance. RAM speed has only increased by around 30mhz, and since it uses 1.35v RAM, I’ve raised it to 1.5v to ensure stability.
I highly recommend trying Offset. It’s comforting to see your Vcore drop to 1.00v when you’re relaxing and not under stress. This gives the impression that your chip will last longer.
The SB Chips are still the odd ones out. If you had an LGA775 chip with a very high Vcore, things would have been tough this time. But honestly, I think Intel has a random Vcore generator and is testing CPUs on machines that print the VCORE. To be honest, I only increased the VCORE by 0.04v and I’m around 45% overclocked.
Good thing OCing takes time, but it’s definitely worth it. Knowing I’m gaining about 45% extra performance for a few hours of free time without any extra cost makes it a solid choice—assuming you’re confident in your setup and cooling.
The machine bluescreened after a restart—6 hours of smooth Prime performance, no issues while browsing or watching videos. Pressing the restart button triggers windows to close and displays a Blue Screen. At 4.6ghz @ 1.34v, it's still slightly unstable according to Linx, especially with high memory usage. I plan to experiment with voltage adjustments tonight and try adding 0.005 incriments of power—things are getting pretty intense.
Wow that's frustrating! I really don't get it. Perhaps a tiny 0.005V adjustment would bring it to full stability.
I experimented with 101 (BLCK) x 46 (Multi) at 4.62Ghz and added a 0.010V bump in Vcore, but I received a BSoD 0x00000101 within ten seconds using Prime95.
Next, I tried 1.25 x 36 x 100 for 4.5Ghz just to boost my memory to 2000Mhz, though even at 1666Mhz with the memory at 1666Mhz, I couldn't enter Windows. This is with the Vcore I use for my 4.6Ghz overclock...
It seems I might need to start over if I want that 1.25 multi setting.
Yeah, I'm gonna play serious with these Voltages now - I've got Offset voltage down to an art form now
😛
Basically its a combination of LLC and Offset voltage you use. You can offset it + and be running 1.42v for example, but if you set LLC to regular it will use Vdroop and drop it to 1.35 lets say under load. Now you may think, 1.42v under light load is going to be bad, but under little or no load it throttles to 1v @ 1.6Ghz anyway with the offset mode enabled.
You can run it on medium, high, Ultra High or Extreme and this will change the load volts, then you have the option to change the offset (+) or (-). The combination of the LLC and Offset settings creates an amazing level of control for load and idle voltages. I have a LAN to go to on Friday so I'm hoping its 20 pass IBT Maximum Burn stable by then. After ive ran 20 passes of IBT ill leave Prime 95 overnight and if theres no errors then Im going to leave it at that once Ive tweaked the voltages to what I want.
Are you talking about your SB-E System?
If so SB-E BLCK Overclocking is pretty much unlocked - the new i7 3820 has a locked Multi, but it can still be clocked to ~4.8ghz stable due to the fact that you can raise the BLCK to 180+ and still have a stable system
