Switching from intel to AMD , any tips and tricks I should know?

1 : Anonymous2021/11/26 16:10 ID: r2qqli

Basically wondering what tips and tricks you guys have?

Always been on intel for God knows how long so I'm used to all the bios settings and things like that

What things are different on a AMD board and bios settings, like what should be on or off etc?

Going for a 5800x with a gigabyte B550 most likely so it will work out of the box , only have 2x8gb DDR4 3000 XMP enabled , will be getting new RAM in the next month's also but stuck with these for now

Should I be getting 3600mhz C16?

I know a lot about parts and building own pc over the years but moving to AMD I don't know anything

Had my 7700k delidded and over locked to 5.0ghz with a Hero VIII board

EDIT - Forgot to mention the CPU and Mobo will be xmas gifts so on a strict budget and was leaning towards the 5800x, and taking to opportunity to upgrade because i have issues with my PC after dropping it a few inches one day, after testing everything for weeks, its the CPU or Mobo, so taking the chance to upgrade

3200 CL14 is pretty much the best bin. You can manually overclock it a bit more than 3600 CL16.

But if 3600 CL16 isn't more expensive and you don't want to bother, just go with it and enable XMP.

Ram speeds and latency have bigger performance gains than overclocking the CPU. If you do decide to overclock don't run static voltages.

First obvious thing, no delidding because solder & delicate interposer. Just get a decent cooler with a little concavity for a solid mount. Power density runs high and the CCD is off center, so a cooler that was good for 7700k may not necessarily rock here. Your sample may run hot or just warm. There's a lot of silicon/binning variation, or at least there was this past spring with the ongoing shortage.

Secondly, sometimes Zen3 overclocking isn't worth the time, especially if you're on a hot chip. Not only are there so many cores to bin, but you'll partly give back the high stock turbo with an all-core overclock. If you have a cool running chip, that's great and you can simply lift your frequency limits to thermal cap and get both great turbo and all-core. It's just that if you start undervolting, stability testing is more complicated because of needing to touch all points on the v/f curve - one way to do that is by fiddling with the max frequency under Windows power settings during a round-robin 1C stress test. A lot of folks fail to check for this and it looks stable under stress but crashes at idle.

Lastly, RAM overclocking is well alive and recommended, mostly in minimizing latencies at the max speed that retains a 1:1 clock ratio with the memory controller. That could be 3600, 3800, or 4000 - again, depends on your sample.

Don't use Corsair RAM, they don't work with Ryzen very well. In the UEFI firmware, enable secure boot and tpm, and set every possible AMD PBO (precision boost overdrive) option to enabled, and try to get the core voltage to 1.3v or lower. Mobo brands like ASUS and MSI like to have voltages very high when set to auto, all it does is decrease the lifespan of your cpu.

Some terminology is different, sometimes motherboard manufacturers still use the Intel terminology with AMD boards, some don't:

X.M.P. is called D.O.C.P. for AMD, because that's AMDs own term for ram oc profiles.

VT (virtualization technology) is actually called SVM for AMD.

Other than that, expect better temps, less security vulnerabilities, and better bang for your buck value when it comes to cpu and motherboard combos, enjoy!

isn't XMP just D.O.C.P only for asus boards? for my X570 aorus master its simply XMP, while I had a 6700k on my asus maximum ix hero it was D.O.C.P.

ID: hm727uq

For asus boards, it's d.o.c.p. for gigabyte boards, it's e.o.c.p. the rest still use intel's terminology.. I don't know why I made it seem different, my apologies

I'm using 32gb Corsair vengeance lpx with my 5900x no problem

ID: hm732u3

Looks like you didn't get a pick from the shitbin, happy for you though.

ID: hm6yp32

Corsair vengeance LPX here. Had issues with the ram for over a year and then worked after a BIOS update. Not exactly sure if it was a ram issue or a MB issue. 16gb worked fine with XMP, but 32 was always wonky before the BIOS update. The XMP settings were always wrong with 32 and wouldn't let me manually set them without BSOD. Works fine now.

Why not go with 12th Gen Intel?

ID: hm69vun

Currently on a budget and the 5800x is down in price

Edit - forgot to mention its a xmas gift from family xD

ID: hm6ceni

I did it for the downvoted, but seriously…. 12700K is a better deal paired with DDR4.

New Ryzen's are optimized of 3600MHz RAM you will want to find the lowest latency like CL-16. You can buy 3800MHz CL-14 for around $30 more and set the RAM frequency to 3600HMz in the BIOS.

Infinity Fabrics performance gains at 3600MHz are greater than increasing the RAM.

The Ryzen has different power management than Intel. When the CPU detects a small load the power consumption will increase resulting in a thermal spike. The Ryzen is increasing power in advanced expecting a heavy load. Theses spikes take a bit to mentally accept and are source of concern for new Ryzen builds.

Do not use Corsair RAM.

ID: hm63kvl

Can I ask why?

ID: hm697kt

If you were/are into overclocking, the vast majority of Corsair's mid-tier ram seems to be Samsung C-Die or SKHynix CJR/DJR, which aren't great dies in terms of performance.

Even if you aren't doing overclocking, the XMP bins are pretty awful for their prices; with other brands, you could get the same performance for cheaper, or better performance for the same price.

ID: hm65y94

They sh*tbin, making their kits unstable and more often than not they cannot hold their XMP properly without throwing errors which cause system instabilities.

There aren't really any differences to note other than if you want to look into curve optimizer.

Ram clock matters: pick 3600mhz if you can. Plug your CPU and ram. Get used to your rig and then, you will be able to play with bios settings if you want extra performance.

So you have waited so long and now that Intel something really good you are going AMD route? Interesting

ID: hm6yx0s

I haven't really waited and its more i have to buy a new motherboard and CPU because i had a issue one day were i dropped my PC a few inches from the table and it screwed something up with my CPU or motherboard ( after testing everything i could separately)

not only that but its a xmas gifts from family so im on a strict budget, not only that but i play 3440x1440 ultrawide so the 5800x is good for me and always wanted to get off intel

ID: hm7o6ut

Youd be better off with a 12600kf than a 5800x, pricing ends up basically the same after factoring in CPU+motherboard costs

Make sure you download send install the latest chipset drivers. Check for latest bios too, might have some relevant updates

13 : Anonymous2021/11/26 20:06 ID: hm6w4zx

My advice is to wait it out a little longer and see how Zen 3D performs. According to AMD, they will be released in H1 of 2022.

Make sure your bios is updated, make sure windows is fully updated, and make sure you download them amd chipset drivers from amds website. Each of those can have a profound improvement on performance for amd.

Do a full reinstall of windows, there are performance bugs in windows when switching from intel to amd cpu.

16 : Anonymous2021/11/26 22:46 ID: hm7gl8t

Fresh install of windows had a friend who went from intel platform to Intel platform never doing a fresh installation with no issue and then had bluescreens when they got amd wouldn't even boot
