Is my 4770k to blame ?

Hi Guys,

I bought the Infinity Tesseract back in March and I've had crashing issues with it from day one. I first thought it was one of those things with PC's and my particular combination wasn't particularly friendly and of course windows can be a bit touchy. So I soldiered on with it, putting up with crashes on a daily basis.

This last week or so I've been thinking that something isn't right for me to have to hard boot the pc every day, sometimes up to 5, 6 times depending on what I'm playing. So I contacted OCUK with this complaint and was advised to download Unigine Heaven and Prime95 and test the pc.

Unigine ran fine for an hour or more.

Prime95 would not run for longer than a few seconds without crashing/freezing my pc. I tried that 3 times and each time it crashed. First time it was with a blue screen error WHEA UNCORRECTABLE ERROR, the other two times it was just frozen on prime95 and I couldn't do anything other than turn off the pc with the power button. This was with vcore up two notches as advised on here a while back after having a lot of blue screen crashes previously.

I then turned off the overclock and ran prime95 again and the program ran fine without crashing.

I tried again with the OC on and the original Overclockers vcore setting using their number 1 profile, and it crashed again, three more times with the error message CLOCK_WATCHDOG_TIMEOUT. This was the error message that I used to get all the time and why I was advised to add that extra vcore.

Anyway I've been emailing OCUK and sent them the pictures of the BSOD's, OC have said :

"it looks like your CPU is failing and it is unable to handle that 4.7 overclock.

Due to the issues you are having I recommend that we get the system back to repair the leak and fix the blue screen issues."

This is something I really didn't want as for one thing I'll have to go without my PC for a while but mostly because a leaking PC will have to go into carriage with notoriously overzealous delivery guys.

Yeah I have a leak too. I posted some time ago that I was losing coolant and after I just serviced it with some new coolant it was clear that the fitting at the bottom of the res was leaking. It's not a fitting I had touched and it only leaks when the tube is touched so it's a bit intermittent but still dodgy especially with all the movement likely in an RMA.

I just wanted to know if you guys agree with the diagnosis and the CPU is basically kerplunk ?

Has anyone experienced this same issue?

Sorry for the loooooong post :(

For the money you have spent on that, it just needs to go back mate, no two ways about it.

Sure you could run it the CPU and stock and fix the leak but whats the point, just get them to sort it. Overclockers are really fast on their turn around, just get it done asap and bite the bullet for a few days. The CPU isnt happy with the overclock you're running hence the crashes and instability.

Never buy a pre built from OCUK... from what ive heard they don't even do proper stress testing on the overclocks.

And remove the fluid before transport.. I'm sure OCUK will put some in the loop...or put your fluid in the bottle and send it with the case?

Thanks guys, it looks like I'll have to bite the bullet and get it back.
They owe me a bottle of Mayhems Orange anyway as I paid for two with my PC and I never received the second unused bottle as it only take 3/4 of a bottle to fill up my pc at most as I've just found out.

OK another question. Since this PC is going to be sent back for repairs I want to make the most of it and get something done on the pc. So at least I'll have a reason for sending it back other than a fault of OCUK's.

Any ideas what I could get done, for around £400 to £500 ?

At the moment I've just converted it to UV.
 
I upgraded to the blu ray drive and a Sumsung 1TB SSD. Other than those the system was the standard Infinity Tesseract.

- CPU: Intel Core i7 4770K Watercooled and Overclocked to 4.7GHz
- Motherboard: Gigabyte Z87X-OC
- RAM: Team Group Vulcan Orange 8GB (2x4GB) 2400MHz C10
- Graphics: 2 x AMD Radeon R9 290X 4096MB Graphics Cards in Crossfire & Watercooled
- Cooling: Full Custom Watercooling Loop, Mayhems Orange Pastel Fluid
- Primary Drive: Samsung 840 Evo Series 1TB SSD
- Secondary Drive: Seagate Barracuda 2TB SATA-III Hard Drive
- Optical Drive: LG Blu Ray RRW
- Audio: 7.1 Channel HD Audio with SPDIF I/O
- Operating System: Microsoft Windows 8.1 64-Bit
- Power Supply: Corsair RM 1000 '80+ Gold' 1000W
 
Blimey, that's an amazing spec. I'd be in bits paying that kind of cash and finding out the system wasn't running reliably.

I guess you could maybe up the ram to 16Gb as 8Gb is kind of the minimum these these days. Other that that I don't think there's much you could improve on,

I know that not all chips will run reliably overclocked but I take it if you buy a custom built pre-overclocked rig from OCUK that they have to guarantee that the system will run at that level. I presume they can't ask you to reduce the overclock if it isn't running reliably?

Sorry I should have said I'm running it on a Sony Bravia 55inch LED. I was going to get a 4k tv but at the moment the pc's are not quite ready for it with ultra settings in my opinion. I'd want 60fps at ultra settings in 4k if I was to upgrade the tv.

Hopefully that will be something I can do in a year or two as prices come down even further and pc's are able to cope better with it.

silvagti, yeah the RAM has always bothered me being only 8GB but upping to 16 will affect the overclock. However, when I knocked my overclock back to default settings I noticed that gaming didn't really suffer too much. So a small drop in the cpu overclock would be ok for me. A good compromise I think.

I've also been thinking of getting them to fit me a 3rd R9 290x and getting a triple bridge. However, they don't have any of my cards in stock by the looks of it. I have 2 sapphire battlefield 4 edition cards, can I get a 3rd card that doesn't match 'exactly' ?

Thanks for the input so far guys, I really appreciate it.
 
As far as im aware with crossfire as long as its the same family it will work ok. so another r9 290x will be fine. you can run a 7750 with a 7770 as theyre the same family they both would run at 7750 speeds.
 
I don't think it's worth spending anymore on it right now. It's a beast of rig already to be honest. Even the extra RAM isn't worth it if you're just gaming. Plus, it could limit your max OC too.

Just send it back and get it fixed, your issues are unacceptable and you should have returned it on day one for the problems you describe.
 
^ Why didn't you return it straight away? OcUK should sort you out anyhow, get it fixed ASAP!
 
Thanks guys for the feedback. I didn't return it straight away because I wanted to get to the bottom of the issue without risking a £3,500 rig going through the delivery process. There were a number of things that could have been responsible at that time and it's not until you've hit the nail on the head that sending it back would be an option for me. It sounds a bit silly I know but despite spending that sort of money on a pc I'm not a rich person and when I do save up to get something nice I do my utmost to keep it that way. I'm obsessive and I'm like that with my cars too :)

Well I've got it booked in for pick up and I'm getting the third 290x fitted after confirming with OCUK that it's fine to do so. I'll obviously need a new waterblock and they are getting a triple bridge for me. The are fitting a backplate to my top card too. I didn't think it would be necessary on my other two as they are hidden but if it turns out they could use one too then I'll order another two.

I had to switch my psu from the 1000w Corsair to a 1200w which I believe will be the Superflower platinum.

I'm also getting the memory upgraded to 16GB while it's there. I done some tests with the overclock on the cpu and even with the oc off games didn't suffer much at all so it's going to depend on the game I suppose and they are going to try to get a 4.7 oc on it anyway. As long as it's in the region and stable I'm fine with that.

I've noticed that 8GB can be a little restricting with certain games and switching between programs but that could possibly be down to that dodgy cpu too. It's an upgrade I wanted to do before I got the pc ordered but finances were a little tight then.

So I ended up spending way more than my initial budget but my mrs is great, she'll agree to anything. But there was a payoff to all this and a little boy will be joining our family in about 8 weeks time now.

I've just finished painting my case window and switched the system over to UV so after I get it back it will finally be what I wanted from the start. Then I'll likely start planning for my next rig which I'd like to build myself as I've enjoyed doing these little jobs. I'll get some pics when I get it back from OCUK next week. Thanks again guys, I appreciate your input.

You must have a lot of money to burn to get 3 290x's for 1080p but glad you got it all sorted

If I feel the pc has enough power I'll likely get the 4k tv sooner rather than later. I also play my games with supersampling on when it's available and as you know that can be a hog on the frame rates.

It's all up to you man, thats the beauty of pc gaming you can always push to get the most power and upgrade as much as you want to suit your own needs. You might find yourself waiting a few decades to supersanple at 4k though :D
 
lol, yeah that would be stretching things for quite some time eh. I got out of the PC stuff some time ago because of the cost but now I've got back into it in a big way and things are way more pricey too. I do find this modding fun though and I can see me spending more on this pc soon.

My eldest son will get this rig, maybe in a year depending on what becomes available over the winter period.

What a lucky son you have eh? Can I be your eldest son ;)

And the gtx 880 should be out then
 
Depends if you're house trained Resa :D

Actually he's not so yeah, why not ;)

GTX 880 would be just the thing to push me to a new rig so here's hoping.
