Question Zen 4 builders thread

[Markfw]

I know its early, but as someone pointed out, I better get my ram now before the scalpers are all over it.

To go with a 7950x, what do you think of this ram:

I jumped on Zen 1 (1800X), Zen 2(3900X) and Zen 3(5900X) day 1. But this time I am waiting for X3D units. I still do a fair bit of PC gaming and it seems to me that ever since modern boost algorithms improved so much that core OC brings diminishing returns, the performance seeking interest has moved to memory subsystems. In that sense I feel that X3D CPUs are starting to resemble the “unlocked” CPUs of previous decades.

Memory ordered!

Corsair 6600 MT/s 32-39-39-76 @ 1.4 vdimm with "Extreme OC PMIC (was finally in stock)
Also have custom copper heatsinks ready for them

Aiming for ~6000MT/s @ CL28-36-36-72 with active cooling

So are you hoping for something with more cores than 7800X3D? Or are you ready to scale down to 8 cores?

Not sure why you would need to change the cooling to achieve those timings at that speed. The DDR5 speed limitation on Zen4 negates any reason to have such memory cooling.

1. Newest information from hwbot discord about Zen4 is that upto 6600MT/s is possible.. Better/active cooling is always recommended with memory OC.
2. I will push timings as low as i can at any given speed, and i'm not afraid of 1.6vdimm and above
3. Stock heatstinks on their vengeance memory is pretty bad/small (Made for cooler compatibly for all big air coolers)

*edit*
My current ddr4 looks like this, and it was absolutely needed to allow me to run the settings i'm running 24/7

Love the speed and the copper! Who made them and can we get even more pure copper fins?

Bartxstore, but they have been out of stock for awhile i think

Custom RAM copper heatsinks for DDR5 / DDR4
€80.00

• Compatibile with DDR4 and DDR5 modules
• For single sided DDR5 – thermal paste on IC and 1,5mm thick thermopad on the back, 0,5mm thermopad for the PMIC (there is a special cut for it)
• For single sided DDR4 – thermal paste on IC and 1-1,5mm thick thermopad on the back
• For double sided DDR4 – thermal paste on IC from both sideds
• Stainless bolts and nuts – no more damaged threads, which makes heatsinks not able to use anymore
• Works with common RAM blocks and pot (Dominator mounting holes)
• 1 set = heatsinks for 2 modules

Out of stock

When is the x3d version comming? - i guess its 24 hrs later than the next Intel cpu. Sad. But yeaa.

Depends on general performance and price. I’d rather get a 7900X3D but I wouldn’t rule out the 8 core.

 

[igor_kavinski]

7900X3D could be very expensive because each CCD will need its own V-cache. They could use a single shared V-cache die but then bandwidth would get halved.

 

[CakeMonster]

Doubt there will be a 7900X3D unless the cost of producing them has gone down more than expected. A 7950X3D has more appeal since its top of the line.

Yeah, I don't see 3D cache on anything but the 7800X3D an the 7950X3D.

 

[DisEnchantment]

For me, since I am getting the 7950x, the 2 in the middle are both reasonable.

BUT... That just MSI, what is the whole platform going to do ?

Man the MSI boards look so good this time around (to me at least). I am wondering why Aorus has quite limited choices.
I will get the MPG X670E Carbon WiFi, to me it looks like a well balanced board rich with features but not overly enthusiast or gamery.

4x M.2 slot
M.2_1 (From CPU) supports up to PCIe 5.0 x4 , supports 2280/2260 devices
M.2_2 (From CPU) supports up to PCIe 5.0 x4 , supports 2280/2260 devices
M.2_3 (From Chipset) supports up to PCIe 4.0 x4 , supports 22110/2280/2260 devices
M.2_4 (From Chipset) supports up to PCIe 4.0 x4 , supports 2280/2260 devices

3x PCI-E x16 slot
Supports x16/x0/x4, x8/x8/x4
PCI_E1 PCIe 5.0 supports up to x16 (From CPU)
PCI_E2 PCIe 5.0 supports up to x8 (From CPU)
PCI_E3 PCIe 4.0 supports up to x4 (From Chipset)

New Trident Z5 Neo kits also looks amazing, timings seem great too


Super excited to test Android S AOSP build on this setup, also curious about QEMU arm64 emulation performance.
First thing I am going to do is 65W Zen 3 vs 65W Zen 4 test.
I cannot wait for those mouth watering gainzzzz.

I hope it will allow me a drop in for Zen 5 without buying new parts. Build is still quite costly even if it is going to make life easier.

I got the Define R5 case. It came today. The ram I have will not fit I don't think, and I had to mod the case just to get the 420 in there. I ordered a kit of
F5-6000J3238G32GX2-RS5K
cas 32, 2x32 gig for 64 gig total at 32-38-38-96 timings, seems pretty tight, but only 6000 instead of my 6600 c34.

So in the first pic, you see where I had to trim a little off the IO shield holder. In the second, its not the right motherboard, but I am sure it will be a problem with the AM5 ones also.

And the last picture is zoomed out. The only items that will be there are the case and 420 AIO, the motherboard is a defunct TR3 x399, but it works for testing I think

Curious about those benchmarks too. Can you please post figures comparing AMD vs. Intel, if you have any from your past testing? Thanks.

Hopefully you can do some comparative benchmarks of both RAM kits before you assemble everything.

Where did you order that sweet RAM kit from???

Directly from Corsair EU webstore
Very fast shipping, got sent from Taiwan on Monday and i got them delivered half way around the globe today

Oh, your obsession with extreme cooling makes sense to me now!

By the way, have you ever tried to take advantage of the freezing temperatures outside?

Might have happened once or twice

Juicy details, please!

lol, went to check on memory sticks after only as few hours to see if there were any progress and the heatsinks came right off

glue failure?

 

[Det0x]

glue failure?

lol no, everything is progressing according to plan..

I wanted the heatsinks to come off as i'm planning to replace stock low-profile cooling with custom copper heatsinks (i linked them earlier in thread)
Like i showed in the picture above, i was giving the memory sticks a bath in thinner (aceton) to make the glue come off..
