Overclocking the Xeon X5660 with a JingSha X58M 2.0

[Razzee]

The motherboard is a Jingsha X58M Rev 1.2 paired with a Xeon X5660.

 

Being a obscure Chinese product, it has no manual.

 

I made an upgrade on the system from an AMD APU to this combo. The PSU (SeaSonic SS350SFE) has only a 4-pin plug for the processor.

 

The system turns on fine, but it shuts down once it gets to Windows' screen.

 

I was wondering if it's due to the motherboard having an 8-pin (EPS?) connector while the PSU provides only 4.

 

Supposedly, the extra 4-pin are to provide more energy to the CPU in case it's overclocked, since 4-pin alone is able to provide up to 192 W, which is a lot.

 

Since the motherboard is Chinese, I wonder if those extra 4-pin aren't actually meant to power something else on the motherboard, like the PCI-E slot.

 

The AMD motherboard had 8-pin and worked well with only 4, but it's not a weird Chinese motherboard with an oddly inverted CPU socket which may have been designed contrary to any existent standards.

 

Basically, I want to know if I must purchase a new PSU as soon as possible or it's more likely the motherboard the issue.

I'd say it's more likely either the PSU tripping overcurrent (a Xeon X5660 is a pretty high power chip, and that is a pretty mediocre at best PSU, it could be pulling too much power considering how the Windows login screen is surprisingly high powered) or the board is faulty.

It looks like a standard LGA 1366 socket to me, those chips were designed to have the logo upside down. It looks just like the sockets on my Rampage III boards. 

 

 

If you really want to check if the 8 pin is wired to have half go to one thing, half go to another, get a multimeter and check the resistance between each of the 12V pins in the EPS power connector. If they're wired up like normal, the resistance between any two should be very low (single digit ohms or lower), whereas if it's wired up like you think it might, there will be one pin that's relatively high resistance.

all i can recommend is that you get a cheap 4 pin to 8 pin adapter like this one. if one of these adapters doesn't work the motherboard could be dead but your psu could just suck and might just not be able to supply enough power to the cpu or motherboard for it to even post. i think this mb is just weird and just needs an 8 pin cpu connector plugged in for some reason unknown. tbh that psu could just be insufficient but i think it'd be better to try a 4 dollar cable from china than to buy an expensive psu with a sufficient wattage.

Based on the power supply output figures, it might be tripping itself due to OCP.

Thanks.

 

I'm waiting for a MSi MAG A550BN to arrive to do a proper test.

 

Usually, the EPS plug is used to power the processor only, but it's a Chinese motherboard which follows no set standards.

The PSU has arrived and everything seems to be working perfectly.

 

One thing that I would like to address is the frequency of the CPU.

 

Although the Xeon X5660 is still a beast at multi-threaded performance, most games don't care about that.

 

The motherboard (JingSha X58M 2.0) does not allow me to change the "CPU Multiplier" to go past 21. I know that this is the safest way to overclock.

 

It does however allow me to change the "CPU Frequency Setting", to any value between 133 (default) and 200.

 

So, if I set it to 200, the CPU will run at 4200 MHz. I have installed a Cooler Master Hyper TX3 EVO and the case has 6 fans, so heat shouldn't be an issue.

 

But in long term, is it good to keep the FSB running at 200 MHz? This kit is not actually for me, but I'd like the CPU to perform at its best.

Those X5600 series Xeons don't have unlocked multiplier so you'd have to overclock them by increasing BCLK anyway.

 

Does the motherboard have a VRM heatsink? In pictures it has mounting holes but not one installed. Honestly I wouldn't bother overclocking at all on a board like that, it looks really cheaply built and doesn't even have triple channel memory or Gigabit ethernet.

[Razzee]

Yeah, I had seen someone complaining on one of the pages that the motherboard lacks heatsinks on VRM, and they posted a photo.

 

Regarding Gigabit ethernet, it's true! I totally missed that! 

 

Now I feel guilty about building a PC with this motherboard for my 10 years old brother. At least I have a PCI-E Gigabit ethernet adapter to make up for it.

 

The motherboard also lacks USB 3.0 (not really important) and SATA3, but the processador and motherboard only costed R$ 200,00 (about USD 40.00).
