Overclocking Gskill DDR5 C30 6000 2x32 (64gb) to 6600, timings tight. W/ 14900 ks UPDATED

[Dr. Dro]

Although this testing 199 cpus at the time was good, but was done with memory they had to work with of the time. Using DDR4 19-20-20 4000Mhz? And DDR5 was a "green" set CL 50 5600Mhz A-Die using 1.4 V MC Voltage (VDD2)....

All article Jan. of 2023 and all testing previous to that date, it's almost Jan 2025 now.

Not sure if this article is valid now with the probably dozen Bios updates (On Z690 no less) since this release also to mention way better memory has been released since this also.

But. I don't see big differences in SP ratings when following the Raptor Lake Mega thread at OCN where people share their experiences with about 1100 pages worth of end user data to browse through.

It's probably still valid to that extent, of course newer DDR5 chips and improved 1DPC motherboards will probably have a different net result

Wow lol 1100 pages.. I need to shuffle through that.

ok seems this has went a long way since I was at work, TLDR

IMC SP Rating - just a number to check on to gauge how leaky (high or low voltages to feed your chip, also for 2 DPC boards it may be an indicator to as where you want to level your expectations)

ir_cow is right when he said not all samples with a higher SP rating are golden, some are just also turds, but in my binning, I have not met a chip yet with a higher IMC SP Rating that acted like a turd, all chips I owned were 8K doable on the Apex Encore and the Aorus Pro X. (that's the only board I have tested with success, I used to have a Dark Hero, it was a certified turd, even with my skill, my Z790-I Strix did better)

edit: 1 DPC is always META..

I’m relatively new to this stuff but unless I’m wrong I would try bringing down that TRAS to 66 or 76. You might get lucky and get down to 56 like I got.

I finally got time to do the necessary testing regime. TM5/Y-Cruncher/LinpackXTreme/Cinebench/Actual Gaming, etc.

I've landed here with this kit...

XMP on this kit is 40-40-40-96. I'm scoring 30K in Cinebench run after run. I could be missing something but anything tighter wont load and it doesnt respond to more voltage. I feel the kit is just "happy" here.

I hit right at 48C on both sticks after 5 consecutive runs of TM5. Gaming for several hours barely gets them warm. They are simply at 1.36V not too high.

Congratulations on stability.

Some of timings seem overtightened and unnecessary, which gives me a slight doubt it's stable over a long period of uptime. But 5 passes of TM5 and y-cruncher is enough for me. It's not a server after all, so who cares on hour 10 it gets a bit flip.

tREFi is asking for trouble over 65k. tWRWR_ sg can go all the way down to 14 on SK Hynix ICs. (Not sure what you have).
