5950x + 2x Viper Steel 16GB 4400Mhz

Hi All,

This is my first post here and looking for some help. I have tried using the DOCP profiles however they fail to POST. I then tried using the DRAM Calculator targetting 3800Mhz still failing to POST.

I was wondering what the best process would be to figuring out what is needed / whether I should look to change ram.

All help appreciated.

Is this a kit of 4 or 2 kits of 2?
If it's 2nd case did u check each kit in taiphoon burner to make sure they are same PCB?
How do they behave when u populate only 2 dimm slots? I'm assuming these are all a single rank ?
Wouldn't hurt to try going for more safe timings 1st to check if they even post. I would be testing with 1 kit 1st to see it's behaviour and find limits
Out of curiosity why such ram? Would rather get lower speed ram with much better timings since you won't be able to get fclk above 1900 in like 99% cases

4 x 8Gb of these run fine at 3800mhz at 16,16,16 Gear down mode ON.
Albeit i use a different motherboard so with experimantation you may get it to run with gear down mode Off.
My first suggestion is to manually set the voltage to at least 1.45V then try it (personally I use 1.5V all the time.)

taiphoon burner

Just a little heads up regarding that software. It's not 100% and guessing ICs in a lot of cases. Good read in the link :-

To follow up - does Thaiphoon Burner confirm they are the same?

 

[Tinkers2004]

yes it will also tell you the version of the PCB, very detailed information within that software

Fair chance your 5950x won't support a fabric clock that high. Set ram and fabric clock to 3600/1800, boot to bios, increase to 3733/1866, repeat until no boot.

I'd also set primaries to 18-18-18-18-36-54 trfc 350, vdimm to 1.4v, soc to 1.05v whilst doing this.

it's very popular set you can find some people using it here https://docs.google.com/spreadsheet...0MWVPcYjf6nOlr9CtkkfN78tSo/edit#gid=321590489

This ram can be set up to anything between 3200 cl12 to 4000 cl16 with relative ease, just need some patience to learn how your set works. DRAM calc goes yolo on some of the timings and this result in no post, so if you adjust something, adjust few things and leave others on auto, so if timings are connected auto will adjust the other one, otherwise you'll never know what fails

here you'll fin rather easy (and low voltage, around 1.4 is more than enough) settings I started from
two sticks are easier than 4, but these are not very tight timings.

also your first step should be to select DOCP profile (one with 4133MHz) but then adjust ram & IF to 3800/1900 without touching other timings. If this doesn't post then you need to check lower IF.
