Overclocking memory *The 70$ PNY 2666* kit
This thread is designed to help with overclocking on budget memory modules. ( At your own Risk!!! ) You know, the memory kits that Thaiphoon burner doesn't seem to read? (I'll show you here how to get the information. Be it complete or not....) But just to let you know, this will be a fresh start OC ABOVE XMP rated frequency. The Kit. MD16GK2D4266616XR Speed Compatibility - 2666MHz, 2400MHz, 2133MHz - 1.2v The Look - Not horrible, but actually reminds me of that Oloy memory if any of you are familiar with it.... Which this kit would be about the same quality if given a similar speed and timing set. Does NOT need these heat spreaders. Totally just for looks. Spoiler The Thaiphoon Burner - Well as you will see here (first spoiler) Eeprom tells us nothing. But if you hit that report button .(second spoiler below)...Which will also tell you the PCB revision of your memory kit as well. As you'll notice, the memory kit is running XMP. I have used it for general purpose and F@H. So far so good. Stable. No heavy load testing yet. (testing using OCCT memory linpack screen shots in the OC posts below) Played some Need for speed at most for the gamers out there. But nothing heavier than that. Spoiler Spoiler Adia64 cache and memory benchmark *Located in the tools tab at the top of AIDA64* (Our initial measurements) XMP rated 2667 16-18-18-35 2T 1.2v 56ms latency but only 35k mb/s read writes. Decent latency and poor bandwidth. Spoiler Check HWInfo64 for Dram temps. =None. Voltage steady good 1.2v VCCIO 1.152v (bios set 1.1150v ) System Agent 1.148v (Bios set 1.1150v ) VCCIO and SA increased for overclock. Also used for daily on B-die, I did not change the values. Are higher than input via bios, but that's how Asus boards roll. OV the shit out of everything. With XMP, on this board, they will default over 1.4v - So users, keep these manually checked! Spoiler
Reserved for OC First OC - Basic XMP activated. Manual adjustment of Dram frequency to 2700mt/s. Adjust Dimm voltage via BIOS manually at 1.25v. Save with F10. CPU model 8700K, default settings. (Memory testing only) OCCT linpack performance reached 20 minutes. Stable operation. Handling daily tasks, browsing, video and gaming works well. Slight reduction in memory latency observed, but frequency tweak didn't noticeably improve bandwidth. Progressing steadily with few changes. (Timings recorded automatically) Next BIOS frequency option is 2800mt/s. Will focus on this one frequency change, possibly skipping validation this time. What's the point? https://valid.x86.fr/cj48r2 Spoiler The next BIOS frequency available is 2800mt/s. Will attempt this change only, setting Dimm at 1.25v. Planning a validation this time. What just happened? https://valid.x86.fr/vz5f3c 53ns latency, bandwidth increasing with higher frequency. Spoiler
Reserved for OC II (manually adjusting timing). Reason: 16-18-18-35 works only at 2933mhz with 1.25v, causing errors at 3066mhz. Changed timing instead. Tested roughly. 18-20-20-40 at 1.35v (other settings remain auto XMP enabled) – 3200mhz, results are decent but bandwidth is limited.
3400mt/s with relaxed timing 20-22-22-42 at 1.35v – everything else auto. Quick 20-minute OCCT pass. Won’t go with 19-20-20-40. Better be looser. I captured this at 3400mt/s and will run a stability test on 3466. Probably won’t hit 3600mt/s with that setup, but we need to reach 3500 first. Expect some interesting results. I’ll stick to the highest possible speed, keeping timings at 1.35v. From what I know about Hynix chips, they don’t usually gain much from higher voltage, maybe up to 1.4v, but it’s unlikely to make a big difference. The thermal performance on the fourth core is really high – definitely stock performance!
Hopefully things improve. Raise them high and then refine the details. Check if I can add a bit more power. Currently it's basic and focused on catching mistakes. Once stable, I'll aim for at least two hours of active testing. Thanks!
Processing at 3466mt/s with adjustments from 20-22-22-42. Performance at 1.35v using AiDA64, gradually improving bandwidth while accepting some latency. On a 2700x it would likely be around 65ms. Testing with 3500 now, results expected soon. Consistent settings throughout.
