Challenging a locked Intel Core i5 4590 to its maximum capacity
current specs are 4590 @3.884ghz with full cores and cache (105 bclk) and 2100mhz ram. If I change bclk to 106, booting into BIOS isn’t working. I’ve lowered ram speed to 106 bclk but still can’t get it to start. I’ve reduced system voltage and adjusted io voltages, but haven’t changed pch voltage. Should I raise pch voltage too? What steps should I take to stabilize 106 bclk? Cooling seems fine for the CPU—my 280mm AIO cooler works well with my 4790k before.
Looks like the issue might be with binning and you likely received a standard sample. The only options here are to run the game at very low temperatures or try turbo unlocking the CPU, which should work on all Haswell chips—even with older microcode. For Desktop Haswell, the process isn’t clear, but it’s worth checking the specific steps for that version.
Have you considered your at the limit of the board... I managed 106.95 BCLK on the z97-K from Asus,...a 4690 nonK but within 6 months the USB ports went to pot and stopped working. While overall stability on the CPU side didn't get worse, even still, there IS A LIMIT to what you can achieve. I doubt you wanna buy a new board just to get 106/107, it's pretty cool where you are and that you got where you did. I should have backed off to 106.something....possibly even 105... 106.95 was my limit, 106.95+ wouldn't boot without errors. You could just buy a couple extras off ebay or whatever and bin them yourself, as opposed to dealing with your 4590 you have now. If you don't want to buy anything, I'd now work on squeezing RAM OC/Timings down if you can't get more speed/bandwidth out of it.
