HyperX 1866 and the M17x R3

Good Afternoon ladies and gentlemen,

I took out the four old RAM modules and replaced them with 8gb (4x2GB) of Kingston HyperX RAM and I am getting nothing but instability. I get the BSoD on a daily bases, the error is normally "driver irql not less or equal". I have tried every RAM profile in the BIOS and im out of ideas. I'm have the A08 modified bios if that helps at all. Any help would be greatly appreciated because what little I have seen when it works properly ( like 5-10 min in game then blue screen) I have gained 8-12 FPS in Crysis 2 and 10-16 In BF3! So this stuff is intense, now just to get it to work right.

 

have you run memtest on them just to make sure they are not defective?

1866 should be running the XMP 2 profile

 

Are you using a modded bios?

 

I have the same question with blue HyperX 1600.My laptop would become blue-screen sometime if I set XMP2 in BIOS.But when I set default in BIOS,my laptop become normal with the memory working on 1333.So I changed the SPD with Thaiphoon Burner to let the memory working with 1866-11-11-11-32.Then no problem happen to me again

 

Interesting find: the modded bios is what was screwing me over. As soon as i loaded in the sotck A08 BIOS everything is running great! BUT throttling is back and is very annoying. I cant even play BF3 for 5 min with out it kicking back to 74Mhz. Any ideas to get rid of throttling with out using a modded bios?

 

you can install the official vbios update from dell (if you haven't already)...it helps a lot. Notice how its marked "Urgent" lol...throttling is much improved

I am also having some issues with the pnp version of the kingston HyperX 1866

if both sticks are installed I get hundreds of memtest 86+ errors.. when I test each stick individually I get none.

I am getting several BSOD's a day and am running the A08 modded bios. I do not have it set to XMP2 but to the default setting right now.

any help would be great!

 

Do you find how to resolve the problem of BSoD ??? I have the same problem too.

 

Did you do a power drain and pull out the cmos battery before inserting the sticks?

 

No! is it necessary to power drain and pull out the cmos ?

 

i didnt and its running fine so far with 8gb hyperx 1866

 

I do power drain and clear CMOS and it change nothing. still same problem.
I thing that M17xR3 do not run KHX 1866 PnP module in double channel at all.

maybe the next DELL BIOS update, this module will be supported.

At the moment i'm running the module at 1600. no problem like this.

 

@99 what version 1866 ones do you have? Because I have the non-PnP blue ones and they need 1.65v to run.

 

I have the grey ones PnP run @ 1.5V

the blue ones run @1866 without problem? what config do you use in bios?

 

The blue ones are rare and not PnP. I enable memory override in the bios for 1.65v and use XMP Profile 2. The thing is heavy memory load causes a sudden shut down. Happens only in a specific app of mine which does load and offload a shed load of memory all the time. The other problem is that naturally, higher voltage is causing the other components to throttle only slightly. This may not be the case for most users because I'm running extreme overclocks. Dialing things back helps.

I use 4x2Gb but most if the time I run it 1600Mhz CL9. When I want to bench I'll switch to 1866Mhz CL9 which is the fastest speed achieved notebook ram out there at the moment, excluding the 2133Mhz one as they aren't commercially available.

 

How do you see if RAM is running at 1333 mhz or 1600 Mhz???

Thanks
