Storm-Chaser

Well that's the end of that. Now, it looks like I have killed the big dog. z5500 subwoofer is shot! Guess my eardrums hold up better than a 12" subwoofer lol..

All bases are now covered. Your RTX 3090 in first place And my GT 710 in last place.

I just re-seated the CPU this morning. I cleaned all the liquid metal off the surface and went back to regular thermal paste for now. No difference, it is still crashing on startup if I have hyperthreading enabled. After it crashes, the system will reboot and I will get this error (from the z840 system alerting): 929-Fatal MCA error Core 0 generic L2 cache generic error - poisoned data CPU: 1 Status: 0xFE20000000000C110A Misc: 0x0000000000000000 Address: 0x0000000000000000 Press ENTER to continue People say this could be a memory issue, but I have spare memory and swapped that in and it made no difference. Reason I am thinking its more CPU related and not memory is because the intial problem happened when I started running an AIDA64 torture test. So it crashed under that load and I was never able to use hyperthreading again. Not the end of the world I still have 36 cores to throw into the mix lol Also, I can upgrade to v4 processors at some point if I can narrow this problem down and say definitively it needs a CPU.

Managed a few good runs for the day.

Nice. Looks good for it's age / mileage. I always go with the MLS gaskets now. I also torque the head bolts to the turbo spec, even if the motor is naturally aspirated (like an EJ25, etc)

Is that an EJ25 motor? How many times have you had to replace the head gaskets over the course of it's life?

do to the obscurity, I thought this new z820 rig would bag a few wins, however, this many wins was unexpected. I'm downloading benchmate for my z820 rig right now. That has some very rare chips under the hood.

Now this is a CPU I can get onboard with. I've been patiently waiting for AMD to step up to the plate and challenge Intel on pure Mhz. I said as soon as AMD has something over 5.0GHz, I will buy it. So this appears to by at the core of my next rig / late summer, or whenever these are released for retail sale.

Filter is okay but why not get something that matches the rest of the build? The current fuel filter makes me think there is a small gasoline engine nearby. Something like this?

Damnit. Only like 2Gb/s away from the lead for DDR3! /img/logo.png storm-chaser`s AIDA64 - Memory Read score: 107220 points with a DDR3 SDRAM HWBOT.ORG The DDR3 SDRAMscores getScoreFormatted in the AIDA64 - Memory Read benchmark. storm-chaserranks #null worldwide and #2 in the hardware class.

Yes I did. It was working flawlessly until I ran a very mild AIDA64 torture test. Which is weird, because it had no problems passing prime or cpuz stress tests.

Almost a clean sweep! Very productive day for me.

I will try that in the next couple days and report back.

The computer is crashing if I enable hyper threading. And the BIOS throws up an error that something is wrong with L2 cache on CPU1. I've never seen anything like it. Its still 100% stable, I just cant enable HTing.

I really cleaned house today on HWBOT Granted, my setup and hardware configuration is quite obscure.

due to the obscurity of this build I am doing quite well with hwbot submissions.

Okay, I guess I can show off a little bit as well. /img/logo.png storm-chaser`s AIDA64 - Memory Read score: 124081 points with a DDR4 SDRAM HWBOT.ORG The DDR4 SDRAM @ 2128.4MHzscores getScoreFormatted in the AIDA64 - Memory Read benchmark. storm-chaserranks #6 worldwide and #6 in the hardware class.

Your 12700K has 10 times the HP of this?

Yeah some of the lower level products from HP are questionable but their high end workstations (like this one) are very well designed and purpose built to handle anything you can throw at it. Active cooling on the ram modules as well.

Looking good my friend! The z840 does not disappoint.

But it's never going to be the same experience you will get from a z840. Plus it has less memory slots.

You are looking at about 125GB/s read speeds with 2133MHz memory, if that's enough than just go with it. Another option would be to get it loaded with just one or two memory modules, sell them and buy another 16 module kit online thats going to run at the full 2400MHz speed. With the 2400MHz memory you are probably looking at 5-10% bandwidth improvement, which works out to like 130GB/s or so. So you have some options.

Most recent safe BIOS is v2.58, I zipped it up and uploaded to this thread, it's just a few posts up.

That's a great price for a z840! Good find. Really interesting idea. Looking forward to see how it works out. IIRC the V4 chips have a maximum supported memory speed of 2400MHz. So your 2666 kit will likely default back to this speed. I think dual rank memory will give you about a 3-5% increase in memory bandwidth when compared to single rank. But it's more expensive. In terms of memory configuration, I would recommend populating all 16 slots. This will allow for maximum performance as it provides you with 8 channel effective memory. The minimum supported DIMM size is 4GB, so I run 64GB in total in this same configuration. Since the 4GB modules are cheaper, this is a good way to go about it. Right on point with processor selection. Thats best in class for the v4 series. I also have a 145W xeon and I noticed upgrading to liquid metal helped with temps a bit, the cooling system is more than capable of 300W but it's always nice to have lower temps in general. EDIT: I would go for the water cooling if that is an option. Very rare to see factory liquid cooling.
