If you are stressing it right that is pretty normal.

1700x 3.8
1700 3.9
1800x 4025
1600x 3.8
1600 3.4
1500x 3.5
1400 probably way above average @ 4050

R5 is a complete lottery.

R7 is 3.7-4.0 so not so lotto.

Better cooling can be counter productive for memory speeds.

Better to run them hot. Set volts at what you know is 1.4 and whatever chip can do it can do.

If you experience cold boot bsods...go to bios let it sit for a minute...then boot, give it time to warm up.

Chipset is a factor. Cpu is a factor pll is a factor. temps are a factor.

Running cold as i have been complicates things. Theres a chart floating around showing memory controller scaling or plummeting shall i say based on temps.

Bsod from cold boot anyone? Now you know why. Also know why im on phase now. Doing imc research. Part of it may be cache related...coaxed my 1400 to 3100...my 1700 was not hearing it no matter what..

Most of these cpus top out around 4025-4050 in real stability...many cant even get there.

Scale with cold...not with volts. Lose ability to clock ram...the gain is negated for the most part especially in "realworld" stability.

In other news...i finally got the k7 to hit 80c on a fanless vrm..still alive.


My chip was really hard to stabilize at 3.3GHz, It seems like if it needed that specific voltage to be set on Vcore and SoC, with 3.6GHz it acted the same way Vcore.

I can run this 3.9G 1.337V without a glitch, 4GHz and I then I need +70mV on Vcore, +15mV on SoC. I wonder how solid is the idea of a relation between Vcore, VSoC and MHz ?

Also having just one rank attached to the IMC gets me to load windows at the 123/126 refclk ( bios post is like 3 secs ) but also limits my OC. Thing is hard to deal with, I still have hope that it may get a lil better with a good bios update.

What is your fav board ( less buggy ) so far ?

Taichi was preety solid once you figure out to set refclock first. K7 seems solid to. Benching wise neither can compete with the C6H it just has a way way more mature bios.

For 24/7 other than the gigas rather alarming vrm temps and taichis wifi/bt device drop all are pretty solid @ 120 ref clock..

I would say those would be the 3 way shoot out ref clock boards.

Prime pro gaming 5 and biostar gt7 would be the 3 way mainstream non ref clock shoot out boards.

I would include msi but until an agesa unlocks some magical ref clock for it.....or they drop price by 100 to fit in the "mainstream contendors" neither likely to happen...they are in a bracket of there own.

I don't know what happened to review sites in the past 5 years...they compare vgas and cpus performance vs price then motherboards they completely forget this.

In that category alone is where i have a huge beef with the titanium.

It can not physically overcome the ability to ref clock and actually lower subtimings...agesa forbids it...you can not modify with a bios what you are not allowed acess to.

That shoves it into mainstream performance...with $100 more price tag than the second most expensive...

Noticed that, Prime X370 3.8G@mem2933 beating Taichi 4G@mem2933 on pretty much everything.

Now, what is that with the Taichi that I have everything set to manual, crap disabled on bios. I boot up to windows, stress it, abuse it, rest it. The next time I restart I can't even get to load windows again, it crashes to black screen. Then I need to enter bios, load defaults and set all the crap again, otherwise it will crash. That behavior only happens if I have cpu set to clocks higher than 3.9GHz.

That is the temp related imc issue at work.

Prime pro is running a very tight ship performance wise. I imagine that is why it causes me drama trying to run 3200 stable.

Pretty much no ref clock board should lose to a mainstream if you drop strap to 2400-2666 and run up ref clock.

Thats the entire point of getting one or its a waste of money.

2933 use 2400 strap 3200 use 2666 strap.

The Prime Pro and C6H (and maybe the B350 Plus too?) have a performance bias option in the BIOS that gives higher scores in Cinebench and others...so take any of those with a grain of salt when coming from one of these boards.

Reg tweaks at the cpu lvl...legit though so no grain of salt needed....comes at a cost...less stability to drive harder.

Yes, I was comparing the Prime I had for a while to my Taichi.
Overclocking with the Taichi allowed me to get higher stable speeds but I am still learning R7's and Taichi's bios.

Right, not saying it's not legit...just that you shouldn't compare scores in CB using this option to general performance level in any other program.

If these tweaks can get you an 1800 CB score at a lower frequency than you would need to get the same score on the Taichi, it doesn't mean your games are going to run faster too with lower clocks on the ASUS. S'all I'm saying.
