***The Official 5900X \5950X owners thread***

What's your cinebench score score with your properly tuned curve, and what is it with curve optimizer disabled?

CB23 is all about the multicore PBO settings. Back before AGESA 1.2.0.5 AMD used to allow you to set EDC to whatever you wanted and you'd still see light core loads use up to 1.5v to boost. From AGESA 1.2.0.5 AMD capped VCORE at 1.425v when you go beyond 140 EDC.

I used to run 270/190/220 for my PPT/TDC/EDC. CB23 can happily draw 250w if you let it on a 5950x.



It was probably late last year the last time I was really benching CB23, but I believe from my archive the above was one of my better scores. 31387. Without better cooling/a really cold day, or even longer spent tuning, anything 31k+ is good. 32k is reachable, but it takes time and/or exceptional cooling on the coldest of days (before we talk about sub zero cooling).

IIRC default 5950x is around 28,000 on CB23.

Nowadays, in part due to the AGESA changes, I just stick to 162/100/140 as my PPT/TDC/EDC. I don't do heavy multicore loads, so focussing more on light single core loads is decent for gaming. That's the thing with these chips, to a degree you're balancing whether you'd prefer better single thread scores or multithread. Obviously there is a perfect middle ground where you balance both, but that, in my findings, needs more than 140 EDC and as of now if you change EDC values in the BIOS you get limited to 1.425v for light core boosting. That does hurt.



My current cores are tuned pretty well with a curve, +100mhz AUTO-OC and at 162/100/140 to do good in normal desktop usage and gaming.

Should we not be monitoring effective clocks? That's my understanding with these AMD CPU's

Yup, effective clock for the really light loads is easy to check with https://github.com/jedi95/BoostTester

Sometimes boosts on regular desktop use don't get caught by effective core polling. Boostester triggers the boost for long enough to check it in HWInfo.

Mines fine, I do get a legit boost to 5150mhz on a few cores on CCD1 under load.

That app is obviously good for making sure you aren't clock stretching either.

Would you be able to do a quick run of CPU-z benchmark or cinebench ST if its easier? Would like to see how much performance im missing out on in ST to see if its really worth going through all the stability testing needed for CO.

I just recently got my 5900x and am cooling it with a Dark Rock Pro. The only BIOS setting I've tweaked is setting the XMP profile on my Team Group memory which is 2 X 8GB sticks 3200 14-14-14-31.

Am I likely to be missing out on gaming performance, or is it minimal gains? Could anyone recommend some "safe" tweaks is they think it's worthwhile?

Even a link to a guide or post would be grand as I can't trawl a 48 page thread to find the good stuff.

Cheers

Hello, sorry if I ask something that may have been already answered: if I buy a 5950X from the OC UK store, can I ask for it to be a B2 stepping ?

It'll almost certainly be a B2 these days. You'd have to ask in the CS section to see if they'd check for you.

Thank you Sir

 

[Kelutrel]

Just for history purposes, at this time (due to the pandemic and remote work) CS said that unfortunately they can't guarantee a specific revision, unless that specific revision is directly stated in the product description on the website.

 

[welshrat]

I can't imagine they are not B2. Ordered mine months ago and it was a B2

 

[Mr Oxide]

You can check with CPU-Z. I have a value of 2 under stepping.

What do you think guys. I've got 2 motherboards. msi b550-a pro and Asus ROG Strix B450-F Gaming

Which one for gaming only and a 5900x

Which GPU? And are you expecting to get a gen4 nvme soon?

Well it's for my son for his birthday. So he's got a 1080ti right now. But I'm thinking 4070 (if priced ok) for Christmas or as soon as I can get one.

He's been asking for more storage so I'll probably get him a gen4 or he can with his Christmas money. But the gen4 isn't a must? Or is it?

Then I'd go with B550, you get PCIe-4 instead of 3 for the small improvements it brings now with the knowledge that if directstorage takes off and makes a difference you are ready.

Will put that one to one side and sell the other.

Ended up with 2 rigs at a crazy low price on Facebook marketing place. Couldn't help myself.

5900x £150
Asus off the MM £40

5600x
MSI board
3600mhz ddr4
1660 super
500m2
120ssd

£230

The rig was over heating so I took a risk and it paid off.

 

[Finners]

5900x for £150 is bonkers, maybe i need to re-install facebook!

Honestly I thought it was going to be broken.

But I checked his Facebook. Pictures matched his house. Had a Instagram link on the side of his car.

So it was like, why not? But of a risk but paid of.

Now my 13 year old son is saying he's not going To the dark side and won't have anything AMD..... Well though luck son

Kids aye!

Tell him I've got an i7-8700 I'd swap with him for it and if he agrees give him a little slap haha
