Glad to hear it is working. You should try adjusting the offset, -0.1250V works for me, but you should try playing around with it, try higher and lower offsets until you find the one that perfectly fits your setup.

As others have mentioned, you're more likely to see improvements using PBO instead of a manual OC. 1.325V might damage your CPU. People have seen degredation at 1.3 and 1.28, but it all depends on your FIT voltage. I have a 3800X. I have found that I get a higher performance improvement with...

Thanks, I will take a look. I quite enjoy tweaking my computer, it really is an enjoyable experience. I definitely know what you mean about temperature sentitivity, I will keep that in mind as I test things. I should include the room/ambient temperature as part of my testing strategy when...

Also, I just ran -0.125V.... which gives a ST performance of 518. (and a MT score of 5062) I am utterly confused by this.

Uh.... wow, that is quite a drop! It just goes to show how different these setups can be. I am quite impressed at your score, I have never been able to get close to 5200. But I agree, I have seen a lot of variation depending on time-of-day/ambient temperature. Based on your results, I am...

I have done a quick test, and these are my results with PBO-4, no voltage offsets. R1 R2 R3 AVG DEV MB MAX 4999 4999 5018 5,005.33 10.97 CUSTOM 4999 5006 5016 5,007.00 8.54 This appears to have no significant difference from motherboard limits. I am going to try with different...

Thanks for your input. I have run a quick test with Single Threaded cinebench 20. Here are my current results: Voltage Offset Cinebench ST 0/Stock 513 -0.0125 508 -0.0500 508 -0.1000 511 What is interesting here, is that I see a definite uptick at -0.10V, and that is strange. I...

Thanks for the feedback. I have tried -0.050 and -0.10, I have found temperature multicore improvement with -0.10. However, it seems that my offset is 8x higher than yours, which concerns me. Is a -0.10V considered a large undervolt? I am going to test with one similar to yours at 0.0125, and...

I have a 3800X with PBO enabled (motherboard limits, 2x scalar). I am seeing 4600Mhz max boosts, and average boosts under load around 4200. ambient of 24, idle 29, cinebench R20 5025-5050 @75C I have tried a -0.10V offset in the BIOS, which resulted in a drop in temperature under heavy load of...

Thanks. I will try undervolting it to see if it makes a difference.

Thanks everyone for the thoughtful discussion. I guess I will have to live with no warranty, and the chance of degredation. I am running it with a 1x scalar, to ensure my CPU makes it to atleast zen-3 release, and I am hoping the next version of zen will fit into the AM-4 socket. I figure that...

Hi Thank you for replying. I am indeed seeing 4675 with 1x scalar in HWinfo. My cinebench results with 10x scalar is 5069pts multi / 519 single. I have absolutely no idea how that compares to other 3800x cpus. Do you have a recommendation for scalar value?

Hi, I have not been able to conclusivley find anything online, so I thought I would ask the experts here. I want to enable PBO, but I don't want to degrade my CPU. I have read that PBO voids the AMD warranty; is that because it pushes the CPU to unsafe levels? I have a 3800X with an MSI...

Hi, I am fairly new at this, so I would appreciate it if someone could point out what I am doing wrong here. I bought some cheap ram from new amazon/corsair, which claims it is samsung b-die. https://www.amazon.ca/dp/B0134EW44S it is CMK32GX4M2A2666C16 Corsair 32GB dual ranked 2666Mhz ram...
