7800x3d pbo guide Determine the PBO range limits of each core based on the data. PPT is the max limit (in watts) that the processor is allowed to use. 7 GHz in Cinebench R23 I'm very happy! This means a drop in almost 20 degrees with fans set to 40%! I've seen a few videos on undervolting. It was a howler of an oversight and, although I have a 7950X, I felt compelled by my own curiosity to buy a 7800X3D because I thought to myself, "Surely they can't be THIS idiotic and Aug 16, 2024 路 7800X3D - PBO -30 all cores, 4. This means that the limited amount of voltage available to the 7800X3D is maximised, and the voltage won't droop under load. At the end, the higher the LLC value, the less UV is applied, helping the stability. The TDP is 120W, and PPT is 162W. BTW I found that a PBO curve of -22 and LLC to lvl 6 for my 7800X3D + Asus X670E-E is somewhat a sweet spot. You can let PBO automatic but use curve optimizer to get more all core freq out of the CPU. Will run tonight and edit with exact numbers. In this video, we will cover five overclocking strategies: First, we rely on AMD PBO and EXPO performance boost technologies Maybe this info is not longer relevant, but I got the exact same issue in my strix b650e board. 05GHz single core, 18286 C23 multi, 1779 C23 single Sage Ryzen 7800X3D - Gigabyte B650 Gaming X V2 - ASRock Steel Legend 7900GRE - G. 2 GHz, and the maximum listed boost frequency is 5.

Reaching 68-69 degrees and 4. I'm trying to set PBO + curve optimizer and coming from a 5900x and reading a lot of guides, it looks like best cores should not be able to have lower negative offset than the other ones. Does anyone have a info about Asus LLC , goes from 1-8 . This is really to share my PBO settings I've managed to tune after sitting on a basic PBO "set it and forget it" settings profile since purchased. (Like with the audio, I don't need/use it. By default this is set to 162 for the 7800X3D. Scores were 17544. The new scores were 18674. 6. It consumes 80-90 W max by default, so lower power limits, or PBO won't help. It's solid for me, so I stick to it. Jul 1, 2017 路 When I first saw coverage of the 7800X3D by the Tech Media/YouTubers I saw a glaring omission on their part with regard to getting the most out of the CPU. Memory Profile: XMP/EXPO Profile 1 Memory Performance/Tuning: Set from AGESA Default to Aggressive My 7800x3d actually ran about 5°c cooler after setting PBO to -30mV and adding +200mhz to the clock speed which gave me about a net increase in a cinebench r23 multiform score of about +800 over stock setting £|³03`Öi ˆˆ¢> ¨ÎÄ 7ôǯ?ÿþ æþ-Sëï |¸¿0AKš!ÅE µØtlgÙmÇîe7ŠdQª˜d1¬ÒâN P§53þqVÄIœ† ¸1Î6«~¬Îøcüo—>ªJ?¦ª ÏåôB € ‘Ô¦-w¹ÝYÃýC†ÈG 1 ¨QW uZóxŠÕy ª}ýÒéôîìHb»c N% Á&ÒM ÂH,Ç& ÜëÿÿSõë÷ ×!Ë y×1 F l *`¹Ý’ƒrd gb[‰‘"·d“ "“ g~ý÷“{ßõ¾iy'): I>R¬HA¦LµÃ;ÈøȸÐØÊû™àÏ` Ð 0g`dè €d May 6, 2024 路 I have done lots of research and tinkering to cool the 7800X3D with little to no performance loss in gaming and everyday workloads.
