Damn 7820x is impressive (my own chip)

Godammit...think my motherboard broke :(. Delidded my 7820x (which went fine), and now it refuses to boot, showing code 00. Upon closer inspection one or more of the socket pins have been bent.

Ordered a Asus TUF Mk II, which will arrive next week. Just praying that it ain't the CPU that's broken...

Watch some videos on youtube about how to straighten the pins. It might be restorable.
 
Already tried, one of the pins is sort of bent in an s-shape. Gonna need some finer tools to straighten that out.

You want one of those round desktop magnifying lights.
You also want a pair of super small tweezers....I bought a pair that are like 2 pins on the end.(20$)

I've done it, it's possible, Good Luck !

Rule #1 of fixing things :
It's already broken.Don't worry about breaking it further , at least try.

:D

That sucks man, hope that it is just the board - it is very rare to destroy the CPU. Did you ever get it to post after the delid? Or have you yet to confirm that it was successful?
 
No, no post at all. Just fans spinning and LEDs, and code 00 on the debug LED screen. Should have the new mobo by wednesday, so will be able to confirm then.
 
My 7700K rig died so I tried out a Ryzen 1800X and wasn't all that impressed. That mobo and CPU are going back to Fry's since my 7820X and Asrock Taichi XE just arrived. Running under a Fractal Design S24 and yea, it's warm running RealBench, it gets to ~80C pretty quick. I'm happy though, I just set it to MultiCore Enhancement so all 8 cores clock to 4.5Ghz and it's plenty. I don't feel the need to push volts and try for more these days. Back in the day of 1Ghz overclocks sure, but for 200Mhz more, I'm good here.

I have 2X 16GB DDR4 3200 sticks so I'm in dual channel for now. From what I've read the performance difference to quad is pretty tiny and I got these back when ram was still reasonable prices..

TLDR, it's warm, but a really nice chip. At the new price of $450 at Newegg I don't see why it's not flying off the shelves.

Its a very very fast chip for multithreaded work as well as gaming. With a delid I am able to run 4.7ghz all cores and no more than 55c under full load water cooled. Before delid it was an easy 90c in the first 3 secs of any real workload.

The quad channel ram has no performance benefit outside of the most demanding and extremely limited workstation application scenarios. However, it sure as hell looks nice to load up 4 or even 8 slots with an RGB ram of your choice. I prefer G Skill Ram for the looks, but thy're all about the same performance wise.

Of course you also get extra PCIe lanes. I am running dual 1080ti cards in my 7820x and the top card gets 16 and the bottom gets 8 so my cards have zero bottleneck.

All in all the 7820x is a wonderful processor and it fills the perfect spot for those of us that want 8 cores that are fast as hell but do not want to spend an arm and a leg to get. With the benefit of quad channel ram (aesthetic of course) and theoretically enhancing performance (theory :p)

Enjoy it. I do not plan to upgrade my cpu until the next gen or more drop in is available, pending Intel still supports X299.
 
Ram density is nice bc I have to move Kubernetes workloads around.
VMs are still a thing, and I want to be able to pull down the AWS AMI 2 for specific builds.
None of my Sr colleagues are ok with the $ of transmitting large volumes when we want to start answering ?'s like "how does Redis 5.0 work when we have X records @ Y velocity in Z use case"

Besides that the 7820x is a capable gamer and I can alt-tab to actual work when Slack starts freaking.
 
Oh it's more than a capable gamer. It's on par with the newest CFL chips. I OC my 7820x to 4.7 and my 8600k to 4.7 and they both turn nearly the exact same single thread score in CB 15. And my 8600k has 3200mhz ram cl16 and my 7820x has 3000mhz cl16.

Anybody undervolt their CPU? Whats your results?

At stock settings with multi-core enhancement (lazy mans OC) on I was at 4.5Ghz on all cores with 1.242 volts. That is of course the auto vcore which is pretty high.

So far I'm down to 1.2v and temps have dropped a bit already, probably around 3-4C load lower running a few hour increments on RealBench to verify stability. I've seen that most can go down to 1v at 4Ghz but @ 4.5Ghz I'm guessing I won't get too much lower than this.
 
I run 4.7 all core but I use speedstep and C states so I downclock when no load is on the chip to save wear tear and energy.

I run adaptive voltage and mine hums along at 1.23-24 volts on average. I am also delidded so that helps immensely with stability and heat removal. I am using a Prime Deluxe mobo so it has great power delivery and I use a full monoblock to pull heat out of my VRMs and CPU at the same time.
 
I can run 4.7 around 1.23v as well. But man I gotta share that the bios' on the MSI x299 board blows chunks big time. The bios is so buggy it adds tens of hours onto my tinkering fun. The biggest bug is that it sometimes doesn't save settings randomly so it won't pass boot up checks, which forces you back into the bios defaults. Fricking annoying as hell when I know this chip will do 5.0ghz on this board as I've benched at that before. But sometimes it will just wig the eff out and stop booting. MSi needs to hire some Asus bios testers asap.

Same. My Gigabyte board runs my [email protected] all day long fully loaded with 1.23v and it's solid as a rock.
 
Latest test at 4.8Ghz CPU, 2.9Ghz Mesh, & 3000 CL16 RAM.

I'm running AUTO voltage in the BIOS, and CPU-Z always shows it at 1.180v, so I'm not exactly sure what the true voltage is.

Careful with that. You really should want to know what the actualy voltage is.

I just checked with Aida64 and the BIOS and it said my voltage was at 2.100v! :eek: But that just can't be right. I'd think the CPU would explode if that were the case.

Can anyone help me understand these voltage readings? I went back in and set my voltage to "Manual" and 1.350v, which is what CPU-Z now shows. But Aida64 shows two readings, one for CPU Core (1.808) and one for CPU VID (1.350). Which one is really accurate?

For what it's worth, after setting the core voltage to "Manual" the system wouldn't load at 1.300v at all. I had to bump it up to 1.350v even for 4.5Ghz.

Someone is having way too much fun! lol. That is a wicked computer, well done and good job! I used two x-acto knifes to fix bent pins on a socket 2011, very much nerve racking but it went smooth. I have a buddy who got a 7820x around the same time as I got my 8700k, it is impressive what the extra 2 cores can do.

Both are but they are different. CPU Core is VCCIN voltage. What you're setting is the VID one. For 4,5ghz 1.35v is a lot. You either have a dud or you're overvolting your CPU unnecessarily. Heck even 1.3v seems alot. You should be in the region of 1.25v max. Reset your bios, see what the baseline VID is for your CPU and start from there.

Wow, read the guides posted earlier! My goodness man you are doing it wrong. This platform is better on auto than not trying at all as with manual. You almost don't even need to mess with voltages as it will set itself to near minimum voltage on auto. Once set to auto, check voltages, note amounts, then trim down using offset, then -, then amount. Read the videos and guides posted in thread.
 
I'm still really happy with my 7820x. It is a monster of an 8-core. I am curious to see what intel will bring out in the future that will work with x299. Any thoughts of when we will see something?

I dont think your going to find much better for awhile, I dont think 10nm chips are going to offer you enough of a bump for you to be worth it and 7nm stuff is highly unlikely to work on your board. But who knows maybe Intel has a rabbit up their sleeves.
 
I found some issues with the 7820X that I had to work around.

1) Photoshop would crash or BSOD the computer instantly when opened. Turns out it utilizes one of the AVX extensions and the chip can't actually handle it and crashes it. There are many threads on Adobe forums and Intel forums detailing this issue. Some just turn off Turbo boost and it fixes it, but a better fix is an AVX offset in the bios. I found it took a whopping -5 offset to make it stable. 24 hour stable Realbench sure, but not 2.4 seconds of Photoshop or Premier lol. Took me a reinstall of Win10 and a lot of head scratching to figure this one out.

2) Gaming had some mixed results. Overall it felt like performance was less smooth and had more frame drops than my 7700K or 1800X had. After some more searching I found that in general it seems the 7820X Turbo modes are pretty inefficient and cause some small lag in many applications. For me once I locked all the cores in at 4.5Ghz and turned off all the Cstates and downclocking feature crap gaming is now back on par or better than the 7700K or 1800X. Photoshop and other more demanding apps are also noticeably more snappy. Another example of Intel half baking this chipset/CPU.

That all said, the system is now performing how I expected it to out of the box. Finally.... It's a beast but it's also a bitch lol.

If you read up on some of the guides... should be public knowledge now to keep avx around 4.2ghz unless you want to feed it lots of voltage.

If you don't like the wait between idle and ramped up, check your core parking status.
 
Core parking is part of C-states if i remember correctly. I really don't care about an extra $2 a month in power savings so I'm just going to keep all of the power saving junk turned off.

It's a windows feature. It can drastically change how quickly cores snap to action. Personally I like my cores to idle when not used, and voltage drops etc that means less wear and tear in the long run.

I would not personally worry about wear and tear, but as an engineer, I fixate on efficiency. I really does tend to be the case that you are using your CPU heavily, or are not. In both cases, things work great even with power saving techniques on. The spikes in CPU usage while web browsing will not be noticed no matter what policy you have.

Never had not one of those issues even with pshop. Wonder if it's a mobo thing?

It probably depends how your mobo is set to turbo the chip. If you enable Multi Core Enhancement you'll probably get the crashes unless you set an AVX offset. At bone stock settings, it seems some will handle the AVX and some won't. Some report it even at stock clocks on the Intel and Adobe forums I've read.
