I picked up a 7800X3D at Microcenter, they had a whole cart full of them. I'll set it up tonight. I want to keep my Windows install as it is, and have done it with past upgrades.
Well, it might not show it on the CPU list, but when you go to the BIOS page at ASRock, there is a BIOS file for 3D cache CPUs. (1.18) so it might just be a homepage that isn't updated. But I'll guess I'll find out...
Make sure your mobo supports it!
The CAS latency on creator targeted RAM kits may be low to ensure stability, just like server RAM. I think most creator workloads are more bandwidth sensitive than latency sensitive?Is "creator" branded RAM very slow cache latency RAM advertised to people who don't know better or is the true latency on them less than your run of the mill 6000 c32 stuff?
The date on 1.18 is March 3 though, before the release of the 7800X3D. They should specifically list which X3D models to make it more clear.Apparently there will be price cuts

It is lower, the stability of the system memory is the most important no doubt."Classic story as with Corsair Ryzen RT DDR4 optimized memory".The CAS latency on creator targeted RAM kits may be low to ensure stability, just like server RAM.

Well I'm not about to check 20 motherboards for BIOS revision dates. I would expect most of them to have similar dates.All of them?
I would think that the support for X3D CPUs meant all three, so all boards that have received that bios update should be good.Well I'm not about to check 20 motherboards for BIOS revision dates. I would expect most of them to have similar dates.
That is what I thought but it's the opposite. I'm seeing high 40 CAS on Team Group's gear.The CAS latency on creator targeted RAM kits may be low to ensure stability, just like server RAM. I think most creator workloads are more bandwidth sensitive than latency sensitive?
The same with sound blaster (forget the company) They screwed me on a $20 rebate years ago, like back in 2001. They wanted the entire flap of the box, not just the code that was on the flap.
Oh no. Sorry. I meant low as in slower performance so meaning higher latency.That is what I thought but it's the opposite. I'm seeing high 40 CAS on Team Group's gear.

CAS takes a back seat with DDR5. If I did my math right the Create Force sticks I mentioned have a 16ns first word latency. The 32 GB kit is 12 ns. The better kits are sub 9-8 ns fw latency.
How does CL28 1T sound? http://www.portvapes.co.uk/?id=Latest-exam-1Z0-876-Dumps&exid=thread...-and-fine-tuned-voltages-and-timings.2610816/I haven't found anything faster than 10ns for a 64 kit.
Not bad, but a rare case. Those sticks use non Hynix dies. Much less room to oc. Ram tuning has been a dying art for a while.
My Trident Z5 Neo 6000C30 2x32GB kit is Hynix A die. I'm running it at 6200c28 with minimal effort. That's around 9ns calculated latency. Great for Zen 4.CAS takes a back seat with DDR5. If I did my math right the Create Force sticks I mentioned have a 16ns first word latency. The 32 GB kit is 12 ns. The better kits are sub 9-8 ns fw latency.
The highest end 64 GB kit they make is 6400c34 with a fw latency 10.6 ns.
I have to go back and look up what some of you recommend me but the gskill tridentz @ both 6000 and 6400 c30 c32 are roughly the same performance, but the 6400 uses hynix and the 6000 uses samsung or micron.
I haven't found anything faster than 10ns for a 64 kit. OTOH the good 96 gb kits are also a flat 10 seconds for a long time now you couldn't get faster than 5600 with high latencies. To get mid 9ns performance you need to drop down to 32 gb unless larger kits exist operating at 6000 c28 which would be a faster kit on paper.
What model number would this be? I only see one kit that's both 6000C30 with Hynix and that would be M die, not A die. It's not a complete list but it's one of the decent ones.My Trident Z5 Neo 6000C30 2x32GB kit is Hynix A die. I'm running it at 6200c28 with minimal effort. That's around 9ns calculated latency.

Edit: I'm positive you have M die, not A die.

Even before seeing those lists I'd read that G Skill was setting aside A die memory for speeds 6400 and up. M die isn't bad by any means.
edit 2: If it is A die and you've confirmed it then this uppends the g skill memo that got passed around in irc about them onlyplanning on using it on higher speed kits due to demand and yields but those have gone down and up respectively. Can you post the exact model number? If it is A die I will get that and save the $10-15 difference between it and 6400.
cheers
For those with a 7950x3d what are the max clocks you have seen? I did some testing on a single core and on the 3d cores I have never seen more than 4.9 GHZ. For the speed cores I have not seen more than 5.3 GHZ. This was testing with cinebench single core mode or using prime 95 on a single core. I want to say the clocks were advertised to boost higher than that. I saw a slight boost if I set the mobo to auto OC 3d mode which I believe set the FSB to 103%, but it was slight.
yep this would be correct based on what information I have for the dies. yes it does sound like they switched off at some point. the ddr5 lists are based on prelim date going back to feb 2022 releases up until this past fall. as i was told the original plan was to run a dies on 6400 and higher with the occasional m die here and there. both clock significantly better than samsung or micron this generation for now, but ddr5 is not meant to be a long term generation afaik.F5-6000J3040G32GX2-TZ5N
The sticker on both DIMMs is S820A, indicating A die. My old 2x16GB kit of 6000C30 was S820M, indicating M die. I suppose there's no guarantee every kit will have A die, or they may have switched at some point.
My guess is they are using Hynix for the Neo line of 6000C30 kits for EXPO due to the tighter timings, it looks like a lot of the XMP 6000 kits are samsung.yep this would be correct based on what information I have for the dies. yes it does sound like they switched off at some point. the ddr5 lists are based on prelim date going back to feb 2022 releases up until this past fall. as i was told the original plan was to run a dies on 6400 and higher with the occasional m die here and there. both clock significantly better than samsung or micron this generation for now, but ddr5 is not meant to be a long term generation afaik.
