Thanks for your reply, Nwoolls(you don't reply to pm's

).

I wanted to know MM displays which speed at the "bottom right" of the page? Five second hash-rate, all time average or the current hash-rate?
Thanks
Current hash rate is shown in the bottom-right.

Alright, thanks! Mind telling the HW's you get when the clock speed of your device is 835? I'm getting 2.85mH/s with like 2-3 HW's when I set the clock speed to 835.
After failing to get my g-blades properly work with BFGM ad MM(
due to no proper support and lack of interest from me{after 30+ tries also it didn't work for me, and moreover I think like this I'll destroy my equipment!}), I've decided to quit these two applications and hold hands of CGM 3.7.2(jmordica fork) - which has successfully worked for me, up to my expectations!

Now I get around 5.7mH/s(2.85mH/s per blade) on my g-blade, with hardly 1-2 HW's. Thanks to all those who gave a hand of help.

I'm glad to hear you were able to find a working solution for your hardware. To answer your question, using BFGMiner (with or without MultiMiner) I get 2.84 Mh/s per board with 0% HW errors on one and 2% on another. The effective hashrate is about the same (2.79 Mh/s & 2.86 Mh/s).
I'm still not quite sure from your posts what issues you had with BFGMiner. Your last post indicated you were getting the same performance I am reporting, but then you struck through the text.
The problem I encountered was - when I posted my first response, I was getting 2.85mH/s with 2-3 HW's - I left the blades to work whole night - but next day when I saw BFGM(I ran the manual miner through MM) was mining at 3.xxmH/s and there were like 50-70 HW's per blade(and they kept increasing). So I had no other option than to quit. Of course MM has nothing to do with this, but there was no other option available in MM to replace BFGM(I have been using MM since I got my first 280x and it works like a charm for me).
and I hope you get an alternative in MM for these blades if possible.
