CPU Upgrades

[Unkindness]

Hi all,

My system currently runs a 8086K with a slight overclock to 4.5 Ghz and a slight undervolt of 1.25 volts. I feel I didn't do too well on the silicon lottery as I've only been able to push my CPU to 4.7 without instability nor can I undervolt lower for the same reason. 

I've recently been able to get access to some heavily discounted CPUs through a friend and I can get a 9900 i9 for about $250. While I don't have any issue with my current setup, I only have a limited time to buy so wondering would a get any decent size performance bump by going to a non-overclockable but undervolted 9900 over the 8086K?

Mainly game and home office stuff but you know yourself, more power is always wanted!

Cheers

I see you have a 2060, so unless you're playing at low settings 1080p esports, then its probably not worth it. Although, for that excellent price, you could probably flip is for a profit

Absolutely not. That 8086K will provide you the best Silicon quality for an overclock to 5GHz and the 9900 is the garbage-bin for OEMs. So if you want to make a useless purchase for a Z-series mobo, then go ahead! Why even bother? You're not even so much better off with a 9900K let alone with that gimped CPU that Intel bothers to call an i9.

 

Cheers!

The fastest games I play would be Dirt Rally and other racing games (don't really play shooters). I usually run the GeForce Optimized setting and get about 100-120 FPS so I'm not struggling too much at the moment. There may be an upgrade to new RTX and possibly go to 4k but not right away.

This may be my last time with access to these CPUs so would I struggle, say in a year or so, running the new hardware and higher graphics with the 8086K?

The 8086k is still pretty decent and so is the 2060, for that workload, this machine should be more than enough.

Mine can't get near 5Ghz. Even cooking itself with 1.6 volts and heating my house, it struggles to get to a 4.8Ghz. That's why I left it at 4.5 and went with an undervolt.

The Z- board was only bought coz I got a good deal at the time since this is my first system and just learned to overclock coz I could.

It is and it runs like a champion but to paraphrase James Pumphrey, I just like Mo Powa, Babeh!

for gaming, it's a sidegrade for the most part.

 

not worth it as an upgrade, but if you think you can flip it for profit, why not.

I'd go for a GPU upgrade first if you do want to upgrade in the future.

If you can sell the 8086K then sure it sounds like a viable upgrade but otherwise paying 250$ for a 33% performance gain is ridiculous.

 

The i9-9900 boosts to 4.6Ghz all-core so it isn't all bad, it's just a bit of a waste for a Z390 board.

I think you might just be overclocking wrong, your CPU shouldn't be anywhere near 1.6V, you'll actually kill it that way and degrade it.

 

I wonder if the reason it struggles to get 4.8Ghz was because you pushed 1.6V through it..

I had it on auto volt in the bios and that was the voltage reported by Hardware Info. I had it at 5 while benchmarking it so once I seen the volts that high, I took the clock down to a 4.7 which was still pulling 1.4 volts. Finally put it at 4.5 overclock to get the reported volts  to 1.3 and then I played with an undervolt 1.25. Any higher overclock or lower voltage, it crashes. 

Any advice is greatly received as I am very green at computer stuff like this

you're not supposed to use automatic voltage when you're overclocking, it always overvolts the CPU more than necessary, I think the reason you couldn't get the CPU stable was because of the temperatures, unless your CPU is delided there's no way you'd be able to tame that CPU with 1.5V or above.

 

with that CPU you're supposed to get 5Ghz at 1.4V or less, 100% of the 8086K's were able to achieve that

Yeah I was learning as I went with the overclocking to be fair. The voltage is on a knife edge as I had it at the 1.4 and went for the 5ghz but was crashing like mad with BSODs.

To be fair, there's probably a likelihood I did a bit of damage to it learning to overclock. It's also an engineering sample so, testing-wise, I've no idea what was done to it before I got it.

I have never heard of an 8086K ES, and I doubt those exist since the 8086K is simply a binned 8700K, how can you confirm that it's legit? I wouldn't set expectations on an engineering sample to perform the same as a retail one anyway

It seems legit but there's barely any information about it anywhere, hard to speak of the quality of such chips since they're so rare

So I believe hence why I'm worried i cooked it!
