8 PACK MEMORY RANGE GROWING: SAY HELLO TO 8 PACK RIPPED EDITION & 32GB KITS!!!

Acolyte · 7 Jun 2020 at 13:45

Just built a new R5 3600 system with the 3600 CL14 Ripped kit. Must say im quite impressed. I cant seem to get boot with the infinity fabric at 1900mhz, so ive stuck at 1867, with the RAM at 3733Mhz. With this RAM speed ive been abole to use the 3133Mhz FAST settings, however the 3200Mhz FAST settings seem just a tiny amount faster, still dead impressive. Now i just need to figure how to try and get a 1900mhz ininity fabric.

Leave your ram at 3600 as you know that's stable then change fclk to 1900 if it doesn't boot or fails aida then drop to 1867 and repeat > 1833. I found the aida 64 system stability memory and cache test was good way to test infinity fabric.

Once you know your highest stable fclk then work on the ram.

FCLK is at 1900 now, it booted straight up and now I'm running AIDA system stanbility, so far so good.

Gosh... I must have a right dud of a 3700x

FCLK capped to 1800MHz. No 14 14 14 14 28 timings and blue screens with GDM off.

My 3600 C16 32gb kit wont post with 14 timings. 1usmus safe timings failed to work for me.

got 15-15-15-28 running at 3600mhz and 3800mhz with FCLK at 1800 and 1900 respectively - just need to game benchmark the hell out of it to see if there are actually any gains be be had.

My latency is worse with FCLK at 1900

1900

1900

That's because your ram and FCLK are not in sync.

It's a 2 : 1 relationship.

So if you run a 1900MHz FCLK your ram needs to be at 3800MHz.

At the moment your FCLK is 1900MHz but your ram is at 3600MHz. When you run your ram and FCLK out of sync you incur a latency penalty.

Nick1881 · 7 Jun 2020 at 15:49

Yea I just realised my mistake there. I ran DRAM calc again for settings at 3800, entered them in and it's booted up but ignored my settings, CPU-Z reports 1200Mhz DRAM freq, it did seem to take a few cycles to post.

Nick1881 · 7 Jun 2020 at 16:04

Cracked it, just need to stability test.

Was just about to order the 3600 32gb kit but has now increased in price when you click through

.

@Gibbo will this be going back to £200 any time soon?

£200 was the pre-order or introductory price, it's currently on offer at £215 so I snapped it up before it goes back to £230 again. I think it's a good price.

Mine is still stable, just spent 2 hours gaming.

They could have at least added/amened the first page to say offer ended :rolleyes:

The 3600C14 kit is £128.99 right now.

Just get the 3200/14 kit and overclock it to 3600 if you only want to pay 200 as they are the same bin just with a different xmp profile.

But is it 100% guaranteed to hit those speeds, on a Ryzen system?

I would be very surprised if it didn't, my 3200/14 16gb kit will do 3800/14. The product page also says high overclock potential of 4000mhz so 3600 should be no problems.

potential != guaranteed, whereas if its sold at a speed it either achieves it or will get returned.

This is very true. But I too have the 3200MHz kit and it easily does 3600MHz with CL 14 timings. Only reason why it isn't any faster is because my CPU can only do 1800MHz FCLK.

I did find somewhere on the web the timings and frequency for the 3200MHz ram and it goes all the way up to 3800MHz.

---

I found the page for my 3200MHz ram:

Under specification you can find this:

CAS Latency

DDR4 3200:CL14-14-14-34

DDR4 3600: CL16-16-16-36

DDR4 3866: CL18-19-19-39

So the ram is actually officially rated up to 3866MHz.

Nick1881 · 8 Jun 2020 at 10:50

My system boot cycles a few times this morning, after a few tries it makes it to windows but my ram is at 2400, but if I go into the bios it's still set to 3800. I tried increasing the soc voltage but no difference.

Dram voltage is at 1.38, should I try increasing it?

Edit - Dram at 1.39v got me back up, but I'm worried about it working on the next boot.

opethdisciple · 8 Jun 2020 at 11:31

You can push the voltage with no worries on these sticks. I run mine at 1.47v.

GregI · 9 Jun 2020 at 05:05

Can anyone get pictures of the PCB for the 3200C14/3600C16 to compare it to the 3600C14? I have a guess that the 3600C14 might be A2 10 layer and the previous SKU are A0 8 layer.
