AM1 5370 OC'D

Asrock board are probably better for overclocking these. If there are four Sata ports on the board, the 2 extra will be using a different controller. Using those ports should mean that you will be able to use drives in AHCI mode when using a bclk over 105.

I have the Asrock am 1-H ITX. I went with it for the 4 sata ports plus the DC input.

You must be right about the different Sata controller as I have a boot ssd, a data ssd and a DVD drive.

Usually* I can only see the two ssd's in windows explorer and the dvd drive pops up when it wants to but doesn't usually show itself in win explorer. I have a bclk of 114 but whilst not new to overclocking I am new to strapline OC's so any help you can offer reference the SAT ports showing would be great.

*Very occasionally only the Boot SSD shows up and not the data ssd?

Nice board.

I'd expect you to have trouble with the dvd drive showing up if it's plugged into one of the sata ports which use the controller which is part of the chipset.

They're all the same colour, but the manual might show you which ones are which. If not, I'd try just the boot drive in each of the ports and see which ones boot with a bclk higher than 105.

I've left mine at 105 bclk and 21 multiplier, which brings it to 2.205ghz. It can do that at stock volts without giving up ahci and usb3.
 
Thanks I could try that as I want to replace the case fans anyway.

I have a 750ti which can happily game at 1080p medium settings 50-60fps but it's CPU limited. It's amazing the difference the 20% overclock made to the cpu. I couldn't even get 30fps 720p before the overclock!

Brill. Please let us know how you get on. Would be good to see some overclocked gaming figures as well.
 
114 X 2.1 = 2.39ghz let's say 2.4.
114 X 2.2 = 2.5 ghz

So an extra 100hz which isn't much in Haswell but could be a lot in this scenario

bear with me i am currently testing clockspeeds and using an R7 360 1200 1625 with a good mix of games

Here's the scaling of the 5370 in valley.

5370 1.6ghz 1600 9-9-9-24 1t



5370 2.2ghz 1600 9-9-9-24 1t




5370 2.8ghz 1666 9-9-9-24 1t

Cool! What overclock settings did you use to achieve the 2.8 and on which board?

I'm using the Asus Am1IA itx. I have a question about your board now you have overclock settings in the bios, do you have the ability to apply offset voltage to the cpu and when overclocking are you able to idle at reduced clocks and voltage?

This 5370 will easily run 2.8ghz, but it requires crazy voltage to get to 3ghz using 136 x 22 but at the moment my 2133 memory and cpu cooler are on my 2600k setup. So I've dialled the 5370 back to 2.8ghz and using 1600 memory oc'd to 1706.

2.8ghz setup consists of
Ahci off-
Ht Ref = 128
Cpu voltage offset + 0.2500
All power savings on.

If you are wondering if you are hitting the pci limit then one way to find out is to reduce your memory strap and your cpu multi and just keep incrementing the ht ref til either system doesn't boot, or drives seem flakey.
Also to note the nb frequency will increase with the ht ref too.
A good place to be is 2.5-2.6ghz.
 
Many thanks your info is really useful.

So my board doesn't have offset voltage or idle support but I'll double check the last one. and I understand the asus board has more of options. What do you mean by ht ref?

All the of options seem linked. I am using 1886 ram but am I right in thinking the higher the ram frequency the higher the CPU oc using bclk? I have some 2400 memory in my own i7 setup I could try.
 
Ok thanks for confirming, it seems there's a compromise in every board, I like your board for the onboard dc power, usb3 header and 4 satas. But I like my board for it's overclocking but it doesn't have a usb3 header.

By Ht Ref I mean Bclck, as you know default is 100.

The memory speed is calculated by multipliers of 4, 5.33, 6.66 or 8. In the bios memory frequency option you would see 800 / 1066/ 1333/1600.

So for example your cpu multi is 21 x 114mhz = 2394mhz.
Your ram speed with the 1600 option (x8 multi) is 114 x 8x2 = 1824mhz.
Your Nb speed will be 8 x 114= 912

So effectively as long as your memory timings are setup correctly you still have headroom to add more ht ref (=117 ). Even then you can just reduce the multi of the memory frequency down to the 6.66 strap and then work out how far your cpu/ht ref can be pushed without over stressing the memory.

2133 memory definitely helps though.
 
Thanks I'm going to reduce the memory then and add a bit more to the CPU.

I'm embarrassed to say this is my 3rd mobo. I bought the el cheapo Msi one then wanted more sata ports so bought the cheaper asrock board. This has less oc options and no dc so I bought the h version. Maybe I'll try the asus at some point especially as a CPU change (to the 5370) is a mobo out job as I use the alpine passive heat sink.

Also got the passive 750ti.
 
Well an update.

I tried to go over 112 today (nb I was wrong above it was actually maxing out at 112 and not 114, although strangely this was giving me over 2.4ghz according to AIDS 64). Anyway the whole sata pci lanes wouldn't work at all I.e I could not see my second ssd at all. Would only work if I went back to a strap of 100! Nothing I could do would change that until I swapped the second ssd sata cable so it was in the same bank as the ssd that I had no problems with. Lo and behold I can now see both ssd's and the second one also appears on the pre bios boot up screen and they are both now very stable.

I shouldn't 'tinker' anymore but I swapped out the 1886 ram stick with some trident 2400 cl10 ram and I clocked the strap to 118. I couldn't actually go any higher without it being unstable. Could be a voltage issue as this mobo maxes out at 1.3?

Either way I'm now running another 125mhz. Going to get some 2133 or 2400 ram as the trident stick needs to go back in my main rig.

Probably going to call it a day there now. Not sure I need a 5370!

It played battlefront fine but kept crashing when I tried to load battlefield so I dropped to 117 and that was then stable.

Battlefront used to run at 15-45 fps it now runs at 45-60 with the bottleneck reduced!
