The motherboard of choice is MSI MAG B650 TOMAHAWK Unlocking stock PBO limits is a quick and safe way to boost the Ryzen CPU frequency and performance, compared to manually overclocking. I have just built my first computer, got windows installed and stuff. 7GHz, and maximum boost clock is 5. This never seems to happen during high loads. Tried reapplying thermal past nothing changed. I also got a good deal on a RTX 4070 and I’m pairing it all with 32gbs of ddr5. If you were to have a main use case of gaming at or under 1440p it likely would not, but video editing and other productive tasks will benefit from it greatly, and 2160p will both benefit from next gen. That cooler won’t be enough for that cpu tbh. ) A 280 should be plenty for a 7900X. CPU: AMD Ryzen 9 7900X. My 7950X on Kraken Z73 idles at 40C and hits like tops 70 in Cyberpunk with +200mhz OC on Ultra + RT. PBO with curve optimizer (manually tested over months) gets me to like 4,5-4,6 ish. ASRock X670E PG Lightning ATX AM5 Motherboard. That, combined with setting a per-core max boost clock of 5850 on ccx0 and 5500 on ccx1 allowed me to enable Medium Load Boostit with full stability on my 7900x. That cooler is underpowered for what you have. The BIOS puts the two options on the same page for convenience. Cpu power in prime95 blend usually hovers close to 100w @ 85c. 575 in Cinebench R20, scores about 8900). Just set the "PBO Limit" setting on the BIOS page in your image at "Default" rather than "Motherboard". the ryzen 9 7900x has 12 cores vs the ryzen 7950x having 16. On Zen 3, undervolting is the new overclocking. skill F5-6000j3038F16G 32GB T30 SSD Kingston KC3000 GPU 1080 EVGA FTW 3 Hibrid (i know Im europe now am5 ryzen 9 7900x is almost same price and in some cases even cheaper than the ryzen 9 7900. When searching the subreddit many people suggest to start at -10 and the slowly go lower until you find the sweet spot. Shouldn't it boost up to 95 degrees, they're designed to run hot, because apparently that's what everyone asked for. Seems like AMD is expecting fierce competition to these. I now have the new x670e hero board with the r9 7900x and a Corsair 2x32 gb 5200mhz kit (optimized for AMD), I have a 850w gold + PSU, 1 hdd, 1 500 gb Samsung Evo 970, 1 Samsung pro 980 2tb and a 256gb SSD for windows. Decreased 7900x power draw by over 50% with only 1% single-core and 8% multi-core performance loss. Primary timings like tCL really don't mean crap at this point outside of marketing, it's the sub-timings that matter more for memory performance; you can have a ~CL30 kit lose to a tuned CL40 kit because of terrible sub-timings. Will it explode? I know this is counter-intuitive for Ryzen overclocking, but try a small positive offset of between 3-5 on your weakest SP rated cores. OP's socket was being supplied 44W. Specs - 7900x Corsair H150i 360mm aio X670E from what Ive seen on this sub the 5900x usually doesnt take alot of negative CO but I would think -10 all core should be achievable and would still yield minor temp improvement. 1Ghz, max temp is below 70C in 3d and video rendering. £65. PSU - EVGA SUPERNOVA P2 650w. A) because it can not endure 105Watt tdp for a long time? B) because its pins are different than 7900x and burns motherboard? C) just marketing. PBO includes three settings – PPT(W), TDC(A) and EDC(A). While true it is also driving these chips into horrendous power draw and performance efficiency percentiles. • 1 yr. My 7900 does 5300 mhz with -30ish pbo and 105w setting at 70-75 celcius. overclocking feature. pn pj df pr sr ff wv xn zk tb
