Mushkin PC12800 6GB Ridgeback Review
Test Setup, Everest and Sandra
Published: 6th October 2010 | Source: Mushkin | Price: £150.39 |

Test Setup
Intel Core i7 930 @ Stock and 4GHz for the overclock tests
6GB Mushkin Redline Ridgeback
ASUS Rampage 3 Extreme
Corsair AX1200w
Windows 7 Ultimate 64 Bit
Prolimatech Armageddon with Arctic MX-3
ATI HD5870
We're also comparing against the Corsair Dominator GT at both 1600MHz CAS8, and 2000MHz CAS8. Finally we're including our current favourite RAM the Kingston T1 Hyper X 2000MHz.
Everest Ultimate Edition
Our graphs are split into two main sections. The bottom two are the Mushkin Ridgeback at 1600 CAS6 vs the Corsair Dominator GT at 1600MHz CAS8. The top three are the Dominator @ 2000, Hyper X at 2000 and the Ridgeback at 2000, all at CAS8.
As you can see the Mushkin rocks and rolls in a big way. In the 1600MHz tests the much lower timings mean it performs exceptionally, and once the overclock is implemented it still romps ahead of the pack by quite some margin.
SiSoft Sandra
Sandra uses a different way of benchmarking memory than Everest and therefore might provide different results. It's this twin attack upon the process that allows us to give you a great feel for the product.
At stock the Ridgeback once again gives the Dominator GT a bit of a pounding. Once everything is overclocked at 2000MHz CAS8 the difference are, as you'd expect, negligable.

Oh and its always on the bottom for youtube videos descriptions however it did use to be the right of the video which is why they changed it to the bottom...people would always confused their left and right relative to the viewer:P
See what I did there?
Wow, I'm lame.

Thanks for the reminder have already looked at the video and taken a print screen of the settings so i get the numbers right!!

tried to run at 2000mhz but system would'nt boot at very similar settings as review. Cant get cycletime of 98 neither 88 nor 100 works, and cant select zero for back to back CAS# delay so left at auto. I will try loosening the timings to 8-10-8-27 or 9-10-9-24, and provide further update. M/B ASUS P6TD Deluxe |
Tried that at 2000mhz and windows started then crashed.
Looks like I have a problem with this set of ram as it crashes to blue screen if you play games (MOH online) I also run prime95 for anything from 2 to 4 mins either on all setting at auto, or 8.8.8.24 or 6.8.6.24, at 1600mhz tried 1.64v as my standard setting and also 1.66v (MB does not have 1.65v) and the same happens. Looks like i'll be sending it back to Aria PC????

You just need to put the time in Im affraid. deffo NOT the ram.
The setting you were looking for is DRAM Read to Pre Time(TRTP) it should be manually set to 8 for memory frequencies over DDR3-1800.
From what you are describing I don't believe that is the issue however, sounds more likely that the Uncore is unstable.
|
I went back to my previous cpu oc of 3.7ghz and OCZ ram at 1866mhz, and stable as any thing prime95's ok and plays MOH ok!! I'll have another go over the weekend. Think I may need to up the cpu voltage from 1.275v to a higher figure. I will give it a go in small increments. I'll check out some of the other posts in the overclocking section for some more tips. |
quick one - if the ram is at 1600 the uclk needs to be 3200 (twice the value) same with mem at 2000 the uclk needs to be 4000
ALSO make sure your tRTP is set to 8 as I said before, thats the crucial thing if you want to go to 2000.
If the ram is running at 1866 thats above the 1600 rated anyways so as we said its fine
You just need to fine tune now your overclocking.
CPU is an I7 920 Do stepping (OEM), stable at 3.7ghz with OCZ PC3-15000 running at 1866mhz so no OC on the memory
I'll re-install the Mushkin and give the settings above ago and let you know what happens.
Was working on this to stupid O'clock this morning and think I'm making head way so far have got CPU to 4ghz and ram at 1600mhx 6.8.6.24 stable. Will do some more work on this later today, as I want to get it really stable then try 2000mhz. Was a bit confused over uncore then found out that ASUS calls that QPI/DRAM, have set this to 1.35v at present with Ram at 1.64v.
Would like to say thanks again for help/pointers, its great to be able to get feed back so quick and from peple who know what they are talking about.

Guys, Was working on this to stupid O'clock this morning and think I'm making head way so far have got CPU to 4ghz and ram at 1600mhx 6.8.6.24 stable.

QPI - 1.5 to 1.55v
Uncore = UCLK that needs to be set to twice the ram speed. its a frequency.
In the ram timings the tRTP needs to be set to 8 (its a little bit down the list of timings)
Ram set to 1.66v.
If you do what we say it will work you are not setting everything correctly
PLEASE read what we are posting fella.

I have just hooked up this kit.
Could I just check that a QPI voltage should be around 1.5v for anything over the rated 1600Mhz?

Sorry for starting up an old thread. I have just hooked up this kit. Could I just check that a QPI voltage should be around 1.5v for anything over the rated 1600Mhz? |
But please read all the posts as there is a lot of other information you will need.
I am sorry to be going over old ground YET again but I just wanted to double check beofre I go for 2000Mhz.
Manually set tRTP to 8
QPI 1.5-1.55v
Timings/Sub Timings as per Video
Ram Volatge 1.64 - 1.66v
and see how I go?
Again sorry for asking thigns that seem to have been answered before, just wanna make sure before I get started.
Thanks
Deffo try the timings I had but remember you are overclocking and your set may be different. If anything you may just have to loosen the times off a smidge.
I still use these in the bench rig and they are rock solid @ 2000 8-9-8-24
Whats the max RAM voltage you would recommmend?
I will halt at 1.66v but will try 9-9-8-24
Just dropped to 8-10-8-24 and stable.
Really really happy with RAM. Recommended to anybody.

Mobos make next to no difference but Mushkin was used in the Saber Review if you go look |
The 2nd 140mm is one of the bigger downfalls of the SA and why the Noctua is a much better cooler.
I've got the Redline Ridgeback 2x4GB 1600MHz (7-8-7-24) kit. I'm using the Asus P8 Z68 V-Pro and an i7 2600K. Do you think I will be able to hit the 2000MHz holy grail with the slightly looser timings, over the kit you reviewed?
I know you probably haven't tested these modules, but can you spare a wild guess?
PS, sorry for bumping thread.
